K.N.
Welcome to the club. I know you'd rather not be here but this is somehow where we ended up and now we deal. I had 3 kids, no issues, before finding out about the MTHFR, and I don't recall which is what but I have both the genes, not jut one. I lost 2 babies, very early in the pregnancies, and was then tested and MTHFR was the result. At that point I started folgard and baby aspirin, and conceived without trouble, but then that never was the trouble. We stopped the aspirin at 14 weeks and my darling boy is almost 9 months old. No complications, no bleeding, and a great doc who let me go in biweekly to hear the heartbeat so I wouldn't worry.
And as luck would have it, while I was breastfeeding we wound up pregnant again. I was terrified, I wasn't on my folgard at the time or anything else, but we are almost 16 weeks along and just fine so far. I am seeing a different doctor in the same group and while we started the folgard again right away (and thankfully we found out really early)he said the aspirin wasn't needed.
It is worth asking your doctor about though. Good luck and I really hope the folgard helps and everything goes well the next time around. It really is possible, I have proof upstairs taking a nap. (oh and get the Rx for folgard, it's a LOT better)
