I've been on birth control before, recently started again, I was on it for a month and when it was time to take my new packet that same day I had unprotected sex. He used the pull out method but I know that there's precum and that it isn't always effective. That was a week ago and I'm actually having morning sickness, cramping, and a fuzzy feeling in my uterus... should I be worried about pregnancy or could it possible all be in my head because I'm nervous? I'm so sorry for asking a silly question I just want a second opinion
