Last month my period was supposed to come Sep 16 I kept getting cramps but it never came. Then the next day my boyfriend and I had unprotected sex he came in me. My period didn’t come. I am on the pill and as soon as I got home I took my pill. Since then I was not taking my pill like I should. I always forgot and had to take double. It’s been a month now and my period was supposed to come last Saturday and still nothing. I took a pregnancy test Wednesday but it was negative. Could I be pregnant?
