I recently started depo that i have used before and had periods non stop. went to see the doctor and he gave me another shot of depo and tranic. my periods have started again a few days back and they are heavier ?

Possible a problem.: Ideally the1st DepoProvera shot should be given with your menses. The shot will block ovulation to prevent pregnancy, along with thickening the cervical mucus to prevent the semen from getting past the cervix. Break through bleeding or spotting is a common side effect, especially after the first injection. Also, the bleeding could be a sign of infection or another problem.
