I've been having unpotected sex with my boyfriend every two weeks. We've been sleeping together since the 4th of July. I got my period July 21st it ended the 24th. I am two days late. Last Saturday we had sex and he came in me three times. There is no sign at all that AF will come. No sore breasts, very very mild cramping and no bloating really. Could my cycle be off? Could I be pregnant? Period why you no come?!?!? P.S. I took a test and it came out negative!!
