the only definite birth control is abstinence. regardless of the kind you use be it pills depo iud etc there is always a chance of getting pregnant however small it may be. i have two friends that got pregnant on birth control. the only way to be completely sure if you are pregnant or not is to take a pregnancy test.
i have the mirena iud and recently i had unprotcect sex could i be pregnant? . my partner didnt pull out before ejaculating and no other form of birth control was used sorry for the over share but i need a straight answer.
