I was on birth control (yaz) for about a year and a half, I went off of the pill on May 30th. I had had my period on the pill about a week or two before I went off of them. Then I had my period June 3 & 4th. Had unprotected sex (I'm married so not sure the exact dates but def. had it at least once or twice two weeks after period & after that). Now it is July 6th so that makes it 3 days since the start of my last period. As far as I can remember my periods were on time before bc but always just really light and short. I know that going off bc can mess with your period . . . took a test I think it was Wednesday July 1st . . . negative. Could I be pregnant or is it just from going off pills?
