Unprotected sex @ end of third month b4 nxt depo-provera shot, am i protected? is it too early & possibe of gettin pregnant?

Depo Provera (medroxyprogesterone): Depo Provera (medroxyprogesterone) is effective approximately 2 weeks beyond when the next injection is scheduled. You said you are at the end of the 3rd month. That should be 12 weeks so you should be protected.

No worry: Yes the Depo-Provera shot is effective for the entire three months and the is a safety margin that makes it unlikely that a woman would conceive even if she was two weeks late getting the next shot. The likelihood of getting pregnant would be less than 2%.
