I took low-dose aspirin up until 14 wks when I was pregnant with my daughter, at that point my doctor told me I could stop. That was my third pregnancy but my first successful birth. I then went on to have another miscarriage (was not taking aspirin) and am now pregnancy again. I've been taking aspirin again since about 4 weeks and am now 13+weeks with a heartbeat by Doppler heard at a 10wk appt. for those of you who have taken aspirin without having bloodwork done, did you take it through your whole pregnancy, or did you stop when you reached the second trimester and how did your pregnancy turn out? I have an appointment at 15w3d, and I'll ask about it then, but I was just curious about what other people have been told.
