Anyone had a partial molar pregnancy found at 12 week scan?

29 replies

We had our 12 week scan and were shocked and devastated to find out that our baby hadn't grown past 6 weeks. I had no bleeding and very strong pregnancy symptoms, awful nausea started at 8 weeks. I had a surgical management of a miscarriage on Tuesday and the surgeon told me that from what he had seen, it is most likely a partial molar pregnancy.
Has anyone had this and did you successfully fall pregnant after? Did you need treatment?

I just wanted to say how very sorry I am and am sending hugs. Take time to grieve. It's a hard experience to go through. A friend of mine had a molar pregnancy and found out at 12 weeks she now has 3 lovely children. Wishing you well lovely. 💐

Sorry you have gone through this, it is horrible. 💐💐

I did, and had a successful pregnancy 6 months later, I was 40.

For me it was found at 2 week scan, no heartbeat. I had had similar symptoms to you.

At the time it was awful. But I needed no treatment and no problems since. They do monitor your HCG levels for 6 months and tell you not to get pregnant for that time so that they can monitor the levels.

The odds are your experience will be the same.

12 week scan. Not two

I'm so sorry for your loss - it's very upsetting. I had a molar pregnancy almost two years ago. Mine wasn't found at a scan though - I had a dreadful miscarriage at 11 weeks, so not long before I was due a scan. I was hospitalised after massive blood loss and they had to remove it during this - it appeared to be causing a blockage. The doc asked if I wanted to see it, but I couldn't. I then had medication to help remove everything else. I had a couple of blood transfusions, but no surgical intervention needed.
I'll be honest and say I couldn't go through that again. I'm fortunate that I have my existing children and, quite honestly, the thought of going through that again has made me not want any more.

That said, a friend of mine had a partial molar pregnancy, and went on to fall pregnant and give birth to a happy and healthy girl a couple of years later. Take time to recover and heal, both physically and mentally, then take it from there. Sending love and a big hug x

I'm so sorry for your loss 💐 it's a dreadful shock and horrible to go through. My friend's daughter had a molar pregnancy which was discovered at 12 week scan and had to go for surgery immediately. I think she was monitored for 6 months to a year after with blood tests. She was told that there's a small risk of developing cancerous cells as a result of molar pregnancy. She didn't thankfully have any further problems though and has gone on to have two healthy children.

Have the medical staff who looked after you not talked to you about any complications that can follow a molar pregnancy?

LadyVioletCrawley · 06/02/2025 16:26

I’m sorry to hear this. Complete molar pregnancy discovered at 8 weeks. Surgical removal as very important all tissue removed due to cancer risk. Blood and urine sent for testing every month for 6 months. Pregnant about a year later and DD now 14. It was a horrible time.

Cornflakes44 · 06/02/2025 16:47

I had a partial molar discovered after some light bleeding at 10 weeks. I had surgery (twice as they didn't get everything the first time) and then had my blood monitored for five months before I could start trying again. I went on to have two babies after that. It felt devastating at the time as I was desperate to start trying again. The constant tests and results just felt like it was dragging out the trauma of miscarriage when I just wanted to move on. But looking back a few years later it has all worked out and it was awful but I don't think about it much now.

Thank you for sharing your story. Yours sounds absolutely terrifying and traumatic. I'm sorry you went through that. I think in these situations, time really is the only thing that helps.xx

Thank you for your reply. They did explain those risks to me, the whole thing is terrifying. I have a healthy 2 year old but since then, have had two miscarriages, the second being this awful one. I really thought it would be even easier to fall pregnant the second time. How wrong I was! Xx

Oh, how sad.
I cannot offer any advice, just condolences

BooToYouHalloween · 07/02/2025 06:35

OP I had the exact experience you described - second pregnancy, horrific nausea for 12 weeks only to find out at 11 week scan it hadn’t developed past 6. D&C confirmed it was a partial molar. I also was then monitored for 5 months with the threat of chemo hanging over me + told not to get pregnant again until all clear. It was a terrible time in my life. Things are better now, a few years on. If you have any specific qs feel free to DM.

OurFlagMeansAfternoonTea · 07/02/2025 07:15

I had a complete molar pregnancy between my second and third children. This was back in 2006.

I had a bit of bleeding at eight weeks and it was found as probably molar at a scan. I had a D&C and then blood tests for 6 months. I was told not to get pregnant in that time. My levels went down in that time and I got pregnant again after the six months. That was a missed miscarriage found at the 12 week scan (at the six week scan the foetus wasn't looking good so it wasn't that much of a surprise). Another D&C and 6 more months of blood tests and not getting pregnant. HCG levels went down.

By this time I was nearly 40 and got pregnant again. Foetus looked a bit dodgy at six weeks scan, but was fine by 12 weeks and she's now 17. I had six months of blood tests again after she was born.

The blood test forms were sent in the post from Hammersmith hospital and I had them done at the local hospital. The information from the hospital was very good and gives statistics on the likelihood of further treatment (from memory it's about 1/12 and I was lucky that my levels went down and I never needed extended blood tests or chemo.

Hello,

Just to say I am in the exact same position as you. Healthy 2 year old, then MMC at 12
weeks and now having a partial molar
pregnancy. The odds seem so unlikely. Hope you are okay xx

FateReset · 03/04/2025 20:03

Sorry to hear this. Take care of yourself.

I had an unexpected pregnancy 2 years ago, when my youngest was a baby and we thought our family was complete. I suddenly noticed pregnancy symptoms, realised I'd missed 2 periods, and the tests were very strong positives. But I felt something was different from my other pregnancies, just an intuitive feeling so I booked a private scan. I could tell from the monitor it was a molar pregnancy. There was no heartbeat, cystic blurry areas. They sent me straight to hospital, where they confirmed it and booked me in for surgery next day. Overnight my HCG went very high, I couldn't stop vomiting, and they did an emergency suction procedure to remove the partial molar. Histology confirmed it was partial (if a full molar you have about a year of blood tests after) but partial they discharge you once you have a negative pregnancy test. I bled a lot after the procedure, but went home next day.

We didn't try for another as ours was unplanned, but it was a big shock and very emotional, especially with all the hormones and surgery.

But I don't think it will affect fertility? I was told not to get pregnant for 6 months. I discussed the procedure with a friend, apparently the suction thing to remove womb contents is the same as she had for a termination. The womb lining is removed and the 'parts of conception' or beginning of the foetus, but nothing else happens medically. A bit like having surgical treatment for a missed miscarriage.

It helped me to think of it as nature going a bit wrong, rather than losing a pregnancy or baby, as with molar pregnancy the foetus is non-viable from the start. The painful thing is thinking you're pregnant, feeling all the symptoms, getting excited then being told it isn't a real pregnancy and could turn cancerous if you don't have the surgery quickly.

I'm so sorry you didn't find out until your 12 week scan. Please don't let it put you off trying again when you feel ready. I felt quite alone having a molar as it's rare compared to the number of women who miscarry in first trimester

I'm so sorry to hear your news, @SkyesTheLimit25
It can feel very very isolating, can't it? Nothing comes close to that feeling of utter shock, devastation, grief and confusion!
However, there is a light at the end of the tunnel. I had the surgical management under general anesthetic. Then I had it again the following week as either some molar tissue was left inside the uterus or had grown back. (Heavy bleeding with clots is something to always get checked after the surgery.)
The surgeries were OK to be honest so don't be afraid of them!
Since them, it's been blood and urine tests every 2 weeks for about 6-8 weeks to check the HCG has been dropping (which it has). Now it's back to almost normal. Once it is, you have to wait 4 weeks before the final blood and urine tests to check its still normal. If it is, you can start trying again if you want to!
Although I feel much better about it all now, when I think back to the 12 week scan and the following few weeks, the same feelings are there and I think they always will be.
How do you feel now? What has been happening? It does get better I promise.
Xx

I'm sorry you went through this. I think that's one of the worst parts, the fact it's so rare and almost impossible to find people who have been through it or even know what you're talking about.
Yes, I've been told that it won't affect fertility thank god. I think I will try again but not just yet. Its such a traumatic time!

So sorry to hear this, I know what your going through, I had my 12 week scan on Friday and the same happened to me, booked in for surgery to remove on Monday, emotions are all over the place and feel so so unlucky as they said its rare and 1 in 600 chance

I'm really sorry that it has happened to you, @Drew25 ! I've read that it's a 1 in a 600 chance for a complete molar but a 1 in 1200 chance for a partial molar. Which one do you have?
The whole thing is awful to go through and your hormones will be all over tha place for a while. Be kind to yourself and take all the time tou need. For me, writing about the experience helped me to come to terms with it all. Write it all down in a journal if you are ready to.
Good luck for Monday, the surgery was OK to be honest. I was put to sleep which helped. Will you be under general anesthetic?
Xx

Drew25 · 13/04/2025 07:35

Thanks for replying, mines a partial aswell, yeah I'll be getting put to sleep i half want Monday to hurry up and be over and done with but then half don't as I know its gone even though I know it already is. How long did you have to have monitoring for after? X

Yes I felt exactly the same as you, I wanted it over with but also knowing that there was no baby was a very hard pill to swallow and a huge huge shock. Feeling quite empty in the womb afterwards made me really sad.
My surgery was 4th Feb, then had it again the following week as there was some left. My last blood and urine test was this week (hopefully), as it was so so close to being back to normal 2 weeks ago. The tests are every 2 weeks. If this one is normal, then I only have one more set of tests in 4 weeks then that's all finished. So, overall it has only been 2 months or so.

I feel better about it all now. However, i felt and still feel like nothing will ever come close to the sadness I felt, the shock, grief, confusion, anger etc. When I think back to the 12 week scan, I still want to cry. I don't think that wil ever change so please be kind to yourself and take all the time you need. Xx

Drew25 · 13/04/2025 12:08

We had two scans aswell before 12 weeks which they didn't pick up any problems which is even harder too cope with the fact we saw the heartbeat etc wish I could just fast forward time now get it all over and done with. Hope everything settles for you now 😊 xx

Arraminta · 13/04/2025 12:27

Yes, I had a partial molar pregnancy back in 2002. Had typical pregnancy symptoms but no morning sickness. Went away for the weekend with DH when I was 12 weeks and started to bleed quite heavily. Came home straightaway and had a scan the next day which showed the foetus hadn't progressed past 4 weeks.

Had a D&C under general anaesthetic, followed by 6 months of monitoring. Told I absolutely must not get pregnant until given the all clear which was June 1st. We were married on June 7th and DH got me pregnant on honeymoon!

DD1 was born perfectly healthy, as was DD2 the following year.
