I got on the Depo-Provera shot almost two weeks ago. I got it a little after my period. How long many days does it take to be effective and work?

In brief: Depo and menses

The depo shot makes the lining thin and is a hormone injection that lasts up to 3 months.
It should be effective with this cycle. Still, you may have irregular bleeding until your body gets adjusted but should still be protected during this time.
