Hi chocolate, I'm so sorry other hear of your loss, I read your post and it really sounds similar to what I've been through, I felt so lost as nobody else seemed to be having the same long drawn out problems so I hope I can give you some reassurance. I'm about 12 weeks post miscarriage now and am finally starting to feel better and, touch wood, my levels are down to negative and my periods have returned.
I found out I'd had a missed miscarriage at 10+3 during a routine scan for NIPT, baby was measuring 10 weeks. I chose to have the surgical management the next day as could stand to wait. Three weeks later I was still bleeding and getting positive HPT's. I had a scan and had retained products so I had another ERPC the next day. More bleeding and still more positive HPT'S three weeks after this and eventually my GP kicked up a fuss with the Consultant who then rushed through my hystology results. These came back as 'query molar'. The hospital consultant, although kind, had no idea about the monitoring or treatments for partial molar, the only info he could give me was from 2012 and completely out of date, I was terrified at this point. I was refered to Charring Cross for monitoring of my hcg levels. I did lots of reading and asked the ladies at Charring Cross lots of questions. I continued to have scans and weekly bloods at the hosoital too under the consultant I still had retained products (awful terminology) after all this. My hcg levels dropped slowly and after 8 weeks the bleeding stopped. I've since ovulated and had a normal period which finally cleared my womb, a scan has confirmed this. My hcg was down to 2 last week which is classed as negative by Charring Cross and I just have to do one more urine test at the end of the month to ensure it remains negative then I will get the all clear.
I still don't know if I've had a partial molar pregnancy as they recheck the hystology at Charring cross and mine has proved inconclusive so it's been send to genetic tests and I should know next week. Apart from the checks required should I fall pregnant again I don't think the outcome will change much for me as my levels have dropped, fingers crossed I should be able to try again come December.
If there is anything at all you'd like to ask please do, like you as well as the grief I've experienced the ongoing stress of all the medical appointments and scans has been overwhelming but I am coming out the other side now and you will too.
There is an excellent support group on face book, it's a closed group and all comments and posts are hidden from your friends, just search for 'molar pregnancy support' and ask to be added. It's really helped me, I'm also having counselling at the hospital which has helped me talk through everything.
