I'm on Birth control (Depo), and I had sex with my boyfriend about 9 days ago and I'm not sure if he ejaculated inside of me, or not... for the past week I have had the influenza virus and have not been able to get out of bed for an entire week with out feeling nauseas, headache, and sweating... but now in the morning I still feel that way and I'm really tired... but at night I am completely fine! as well as through out the day I am sweating and getting headaches when I move around alot, as well as I'm spotting, I don't know if the spotting is just from the depo..... Is it possible that I am pregnant? Should I take a pregnancy test?....
