Hi Im 19 years old and this is my sexond round with the depo shot i took it for over a year when i was 17 but then never went back and now i decided to do it again but this time the spotting is lasting longer and its pretty annoying and embarresing...i got the birth control to ease my mind about having sex but the spotting is making it impossible so my question is how long does it normaly last b4 it stops Thank you :)
