Hi, Danielle,
Haven't heard from you in awhile, and your post caught my eye. I actually had a pregnancy shortly after my replacement. My cardio and ob put me in the hospital, got me regulated on heparin shots, and then two weeks later, I miscarried. This happened shortly before this site was established, and to say the least, I was terribly ignorant about the effects of coumadin on anything. All I knew were the basic facts I got from my doc and the lab tech drawing my blood. My cardio did make a series of phone calls to colleagues and researched this issue for me for several hours before putting me in the hospital, so I felt very well taken care of, but when I look back on it now, and knowing the risks of coumadin crossing the placenta, I just shutter, at least at my own ignorance. Anyway, I've since brought this up with my new ob (now living in a different town) who says it's possible but very difficult and must be carefully monitored by a high risk ob and a cardio. I agree with the other responses. Talk to your cardio and a high risk ob before attempting this. Since I've actually met you and had dinner with you, Danielle, I can tell you're a very rational person who's just doing her homework. Best of luck and nice hearing from you.
