Honestly it is most likely just crazy hormones right now. You should not have a preg. test show positive 6 days after intercourse. That said, it is definitely something to call your OB about. She can answer more specificallly, and may even want to see you soon just to make sure, given your history. I am so sorry for your heartache, I am sure you are in a rough place emotionally!! Your body has suffered a trauma too, and it may take you a while to adjust, so your periods could be off for a few months even. So, again, call the dr in the morning, but for now, I would assume that it was hormones. A friend had a preg test show positive 5 weeks after she had a baby (obviously she was freaking out) but it turned out to be left over hormones. Hang in there and good luck in the future! ~A.~
