Had had sex before starting the birth control now on it and having most symptoms, started working out almost every day and had college finals and things in the past month, missed the last period and it is now almost 2 weeks after missing. Have had 3 negative pregnancy tests and don't know if there could be something wrong or something to do about it, absolutely can't stand kids so a kid is not an option at all. Just want to know if the tests are right, heard some bc can give pregnancy symptoms, and know stress change in a workout etc can make women miss periods, have pretty bad exhaustion the past maybe week and again don't know if that is attributed to stress or what. I am very confused and a little freaked.
