I am 16 years old and I had sex for the first time the same day that I started my period. It was a very light period to the point where I didn't even really notice, the guy did not ejaculate at all and the next day my period was gone. I am scared now does this mean that I am pregnant? Now my period has never been regular sometimes I go 5 months without getting it and I have a regular discharge and it is clear. Am I pregnant.:confused:
