Me and my boyfriend had sex on March 31. I was ovulating and it was unprotected. I was suppose to have my next period April 13, but i didn't. I took four home pregnancy test and they all came back negative. After that, i had my period on the 22nd of April, it only lasted for days. It was not like my normal periods, it was much lighter and my periods are never late and they always last 6 days.
