Okay so my boyfriend and I have been having unprotected sex for over 2 weeks and about a week ago he told me accidentally came inside me. I am on birth control but when I got to college I kept forgetting to take it until recently. When he told me I took Next Choice two days later but I have gone through all my white birth control pills (the ones your supposed to have your period with) and still no period, but i've had some really light spotting and i've been feeling nauseated a lot, especially when I eat certain things or smoke. I'm getting really nervous.
