I'm 25 and have been on deprevera for 9 months after child birth, I had bleeding throughout the duration. I took myself off after the last shot was due which was march 16 it is now April 4th and I haven't had a period since the end of February which is over a month I'm wondering if this is normal considering I never lost my period while taking deprovera?

Oh yes very normal you possibly won't see a period for 6 months or more it can also take up to a year or more to conceive after receiving the jab.
This is a c+p from the leaflet given with the med.
The effect of using a depo provera injection does not cease immediately after you stop taking the contraceptive. Though you may choose to stop it anytime and you may start ovulating immediately, it usually takes a period of 6 to 10 months to regain complete fertility.

Other birth control side effects typically associated with hormonal contraceptives, like weight gain, breast tenderness, and depression, may become lesser gradually as the body gets clear from the effect of the hormonal injection. If you are considering pregnancy after depo provera, you might have to wait as long as a year for the positive signs.

Once you have stopped the injections, drinking lots of water and juices, eating organic vegetables and fruits, and exercising may help the body regain fertility rapidly. Some women also prefer taking a detoxifying session or going to a sauna to clear the body of the hormone.
