After having a baby you are extremely fertile. After I had my baby march 15 last year I bled for a while. I was still bleeding when I got the mirena put in in June. If you had unprotected sex there is a great possibility you are pregnant. If the tests are showing negative call your doctor to verify that it is only your hormones. Also, I tried breast feeding and while I was attempting I was very emotional and if she cried I would bleed like a stick hog, gross I know but if you are breast feeding there is also the possibility that your hormones are just embalanced and you haven't gotten them straightened out yet. Good luck to you.
Thank u so much.. I still have to find a new doctor since I have moved here in Washington last month.. We use condom sometimes and pull out and I know pull out is not reliable..
