I have a ds and dd who were easily conceived the first cycle trying. We have been ttc #3 for a year now. We got pregnant the second month trying but miscarried naturally at 5 1/2 weeks. We then tried again for another 8 months. During that time, I think I may have miscarried again, a chemical pregnancy, but it was not definite - just a feeling and symptoms I had that were similar to my previous miscarriage. I ended up getting pregnant again at the end of those 8 months but at 7 weeks couldn't find the baby and by 9 weeks I was going in for a D&C due to a suspected molar pregnancy. That was last week so I am still waiting on the pathology report to find out if it was molar or not.
I've been trying to look up causes of recurrent early miscarriages and so many of the causes seem like they would be issues that would always have been there. Since I've had 2 easy conceptions and pregnancies, I can't imagine those were flukes so I'm wondering what kinds of causes could there be that didn't exist before but now exist. My ds was born in 2006, dd in 2008 and we started ttc again in January 2010, so it's not like there has been a huge amount of time that has passed. I'm also not old - 33, so I can't imagine my age would make THAT much of a difference. I've had some bloodwork done and the only thing that wasn't good was my progesterone. It was low, so we started taking it after ovulation. I got pregnant the second month on it and started taking it again as soon a we got a BFP. It was a late BFP (17dpo) so I was without the progesterone for about 4 days but I don't know if that made a difference or not. My first miscarriage was without the progesterone. I do find it interesting though that with my 2 live births, I got a BFP on 11dpo with strong pregnancy symptoms already (so I may have tested positive even earlier, and I used a digitial, 50 sensitivity test so I could have probably gotten a BFP earlier). With my first miscarriage, it was negative until the BFP on 15dpo and with this most recent one, it was negative through 14dpo and then I got a positive on 17dpo. I've read that late implantation correlates with a greater chance of miscarriage so I'm wondering if there is some genetic issue or something that makes the fertilized egg sort of "bad" right from the beginning. Any ideas?
