My understanding was that Lovenox does not cross the placenta into baby's circulation, so it wouldn't affect his/her clotting, it would just thin mom's blood making it less likely to clot in the placenta. The downsides that my MFM outlined were theoretical risk of bleeding at the implantation site or more serious hemorrhage if I were to have an abruption, develop HELLP, or require emergent c-section. The other consideration for me in favor of Lovenox is that I spill quite a bit of protein due to my kidney disease which can put me at risk of clotting if the proteinuria gets high enough.....so the benefits may still outweigh the risks of bleeding. I don't think anyone has the "right" answer, so I guess the decision has to be made for each patient.
