I had protected sex 8/30 which was my ovulation day, but he did not ejaculate (Im not sure if he pre ejaculated). I ended up getting my normal period 2 weeks later on time for five days, but after my period ended I'm still getting pms symptoms like lower back pain. I've read online that some people can get pregnant even after having their periods, so I was wondering if there was any chance I might be? (Not trying to be pregnant by the way)
