Me and my boyfriend did not have intercourse but for a few seconds and he didnt even cum yet, but I know some women can get pregnant from pre cum. My periods are usually 23-28 days. My last period was on January 30th- February 3rd. We had intercourse on February 9th. I took three Tests out of paranoia, and they came back negative. Please help, im also moody, and feel oddly in my stomach...my period is due on Monday but im really scared that I might be pregnant.
