7 weeks scan showed 5 weeks - concerned

[Laans1990]

Hi there,

Yesterday I went for a scan and based on my LMP the doctor and I both thought it would have been my 7 weeks scan. To our surprise it was only 5 weeks. The week before I tested my lines were so faint and I got a 2-3weeks on clear blu and this week Tuesday when I tested it was very dark lines and I got a 3+ so I thought all was progressing as it looks like it on the test. Could the dates be off that far along on the scan is it possible? Did I may be ovulate a different date? Can irregular period be the case? I also have no symptoms. The dr saw the yolk sac and all that and he said it looked perfectly healthy for my gestation. But I am worried about the dates being so off. Thank you

Both my pregnancies I had a scan around 8 weeks according to LMP and they were showing as 6 weeks and a day or two. Both continued successfully so fingers crossed for you.

@2024NTU Thank you so much I feel better reading this ❤

I also had a scan at what I thought was 8+0 but was dated 6+3 - now 23 weeks! I had a look back at the calendar and I think I ovulated 5 days later than usual which in addition to the teeny sizes they were working with on the scan accounted for the dates discrepancy. Best of luck to you!

I'm in a similar situation – have been scanned at 5 , 6 and 7 weeks (due to previous ectopic) but while there's been growth each time they haven't yet seen the foetal pole and heartbeat... I've got a retroverted uterus which seems to be making things tricky at scans. They didn't tell me how many days I was measuring so unsure whether there's any hope but have another scan (supposedly 8 weeks) tomorrow which can't come soon enough.

Hope you get good news at your next scan.

@tangobravo thank you for the reassurance :)

@NSC1980 best of luck to you please keep me posted how it goes tomorrow! Will be thinking of you! 🙏

My first scan I would have been 7+6 by LMP but I actually measured 6+1.
I knew I'd be behind as I have long cycles and ovulated late.
I'm now 17 weeks, everything going well, baby still consistently measuring about 12 days behind LMP date

This happened to me too. I had just had the coil removed so think my cycle was longer than I expected and perhaps what I thought was a period was an implantation bleed. Anyway - it was horrible, had to go back three times for my dating scan and I was so worried but baby is now 26 weeks and measuring perfectly. If staff don't show worry, I'd take their word for it - they were v unbothered by what was going on and just reassured me it was a dating issue, rather than baby growing slowly as I was convinced.

@Bramblecrumb I also just removed the coil! That makes a lot more sense and your post really made my day as this week I've been feeling so nervous. Thank you. I have the next scan the 30th of October and it can't come quickly enough. So happy all worked out well for you!

@NSC1980 just checking in to see how you are and I hope all went well with your scan ❤️

Hi @Laans1990. Thank you for checking in.

The 8-week scan again showed growth with a small foetal pole measuring 3mm (no heartbeat yet) which the sonographer said would put me at around 6 weeks (although I rang up yesterday to chat with the nurse who said the sonographer had actually written down 5w 5d). The sonographer said to keep positive as there's been growth and return in two weeks for another scan. It's quite hard to keep positive now as I'm certain of my dates (and had HCG blood tests done at 5 weeks which were well within the 5 week range so I couldn't have been behind at that point).

I haven't had any cramping or bleeding (although they did see bleeding on the scan and prescribed me progesterone) so if it weren't for the early scans because of the ectopic then I would probably be entirely unaware of any problems.

I hope you're keeping busy and managing to stay positive. I think things look a lot more positive for you with recently having the coil removed/being uncertain of exact ovulation date so fingers crossed you'll see a heartbeat at the scan on the 30th. Sending positive thoughts x

@NSC1980 I am so sorry to hear that it wasn't the outcome and growth you were hoping to see on the scan and I can just imagine it is hard to stay positive. But I am happy to hear there is growth and that you will have a scan again in 2 weeks time. You know sometimes biology is just hard to grasp and can surprise us so I am still positive that you are going to have a good outcome and will keep thinking of you. Please keep me posted in the next 2 weeks and I will also let you know next week. It feels like forever and it is driving me crazy. You take care rest up and be good to yourself. Thinking of you and sending positive thoughts your way as well x

@Laans1990 Just wanted to say I'm thinking of you 🫶

@Bramblecrumb thank you so much ❤️ scans on Wednesday next week. Will keep you all posted x

@Bramblecrumb sorry for the delayed response but ended up only having the scan today in the end. Baby caught up and is over 11 weeks now with a strong heartbeat and all looked well. :)

@NSC1980 - just checking in on you, how are you? And is everything okay in the end xx

I'm glad you have updated and baby has caught up.
I had a scan yesterday at 7+3 but measured at 6 weeks. My nausea is more consistent with 6 weeks pregnant for me. It tends to get debilitating at 7 weeks. Nervous 2 week wait to be rescanned!
I had a miscarriage in August so it's on my mind a bit.

@Superscientist so my gynea told me yesterday if it is less than 2 weeks off he is not concerned as I could have calculated period incorrectly or ovulated different date that month etc. You are way less off than I was so I think you are perfectly fine and will have caught up at the next scan 😊I am still exactly 7 days off now but gynea said at the gender scan at 13 weeks it might show a bit differently but he is still not concerned cause we are now going of the scan date. Let me know at your next scan if you want and I will be thinking of you! 2 weeks feel like an eternity right?? I waited from 16 october to 21 november for yesterdays scan it was so tough lol!!
Goodluck and thinking of you!

Thank you. In my head it's 50:50 still hope but I don't feel out of the woods yet.
I have read there can be up to 5 days error in the measurements and then there's errors in ovulation date - I don't track ovulation and then there's variability in time to implant and start growing. Logically I can see how you can be easily behind by 10 days but logic doesn't always win does it! 😆

I have been off sick the last few days with fatigue and sickness and usually work is my distraction!

@Laans1990 So happy for you that the scan went well and the baby has a strong heartbeat. That's great news.

Sadly it went the other way for me and my fifth scan revealed no further growth so a 'missed' miscarriage was finally confirmed and I had surgery the following day (unfortunately they didn't get everything so I'm back in again tomorrow for round 2).

I know your happy ending will bring lots of hope to people in similar situations searching this forum for good news. I hope the rest of your pregnancy goes well x

@NSC1980@NSC1980 I am so so sorry to read this was really hoping and praying for you for a different outcome. Hope the second surgery went okay ❤️ please be kind to yourself and take the time to heal. Your rainbow baby will come. Sending you all mh love and hugs x
