So i am 4 months post partum and around 3 months I was talking with the husband about not having my first post partum period and he said to take a pregnancy test. Well I did it came back positive. I took enough home pregnancy tests that I watch the lines progress and then the last 3 were just negative. The dr did a urine and blood test and both came back negative. So I know the blood test is the end all be all so now that I know I am not pregnant why haven't I started my period yet? Before I had my son I had like 4 chemical pregnancies and with in a week of receiving the negative results I started. It been i wanna say almost a month and still nothing. Those of you who have been in my situation when did you start?
