I had sex on my most fertile day. I am late I had a baby five almost six months ago and I am worried I'm pregnant. I breast fed for 2 months but could no longer do it. I was on birth control the month before I had sex but it hurt and I told him he came in me on the day. My period was supposed ti start on the 23 yet its light today and it's the 25 its like a liggt salmon pink color. I have never had a liggt period like this and I have had three periods since my daughtrr. Not only thatbut I had a mild fever that was 99.9 and it rose to 100.3 then in an hours time went back down to 98.7 could I be pregnant again. I know I had a kid before but its always different.
