On a Sunday, I had unprotected sex and Monday I took plan b. Today is Wednesday and we had unprotected sex again. He did not ejaculate in me, but I'm worried about anything coming out before actual ejaculation. My period calender says that I'm in the part of my cycle when pregnancy chance is low, but I know plan b messes with the cycle. So all I want to know is if there is a chance that I could be pregnant?
