I had sex with my boyfriend a week ago yesterday and he ejaculated in me. I'm currently taking Amethia birth control pills and have been taking them for about a year now. About two and a half weeks ago I lost a pill and took an active pill from the very last pack. I take my pill around the same time every day. I've had very, very little brown discharge. Could it be a possibility that I may be pregnant, or no? Please help.
