I was not on my birth control while my fiance was in Basic training, he came home and surprised me 6/23. I did not have my Birth control on, and we had unprotected sex, several times he ejaculated in me. I had just gotten off my period the day before. I know the risk for pregnancy is low. My birth control is the Xulane patch... If I go back on it, and the week off, will I get my period whether I am pregnant or not?
