I have been on birth control for about 5 months. I take it religiously. Always on time. Occasionally a half hour before my scheduled time but no earlier than that. My boyfriend and I had unprotected sex a few times but he never ejaculated inside me. I realize that there is still sperm even if he didn't ejaculated inside me. I'm worried I might be pregnant because I'm 2 days late for my period. My period started out starting 2 days late and then after a few months it would start the day that I took the placebo pills.
I was very sick last week (the week.before I was supposed to start my period) and was wondering if this could play a role in why my.period is late?
