I've got no experience in this area but I didn't want your post to go unanswered. I totally understand why you're so scared with the background. Have you seen a gynae doc for advice or was it just a GP? I'm hoping by answering this I'll bump the thread and someone might be able to help!
Hi, I have not experienced this but my cousin has had it on both pregnancies, first baby was born at 34 weeks, she then miscarried a couple of times and second baby born 35 weeks, she is carrying her 3rd and after being refered to a specialist has been told she has a very common condition that can be helped by a small dose of asprin. Unfortunatley I can not remember the conditions name but it can be detected by a simple blood test. Dont know if this is relevant to you but she is now 38 weeks and no problems so fingers crossed xx
I also heard that low dose aspirin may help. <disclaimer> I'm not a doctor, but my friend who is a GP said that sometimes something simple like aspirin helps and they don't know why it does. Anyway - the consultant should be able to shed more light.
