You are taking it for pregnancy, right?? Just to clarify, ~most~ people would wean off the aspirin gradually over the course of 3-4 weeks after BFP. But some people have issues where their blood clots too easily and they are given blood thinners (aspirin or occasionally something even stronger) thru their pregnancy and have to come off those at 36 weeks because delivery while on blood thinners is highly risky both for mama and baby. So in that case, if you are told to come off the aspirin at 36 weeks, I would try to start weaning off a little sooner, so like at 34-35 weeks, drop back, aiming to be done with weaning by 36 1/2 weeks. you don't want to take it much longer than 36 weeks because it needs to be out of your system by delivery time both for your sake and the baby's. I woudl also probably go ahead with the Vit. K drops for baby just to be sure his blood is clotting ok.
Most doctors and midwives have not read the most recent research which clearly shows an increased risk of death from clotting and heart attacks when people who were on aspirin therapy stop it suddenly!!! theheart.org: trusted cardiology news and opinions And even if they have, it's like until they see the same study done on miscarriages they can't connect the dots but it's SOOO obvious to me that it just can't be good to drop the aspirin all at once. I think it's a serious thing and we need to be really cautious with it. :)
