When should you stop having irregular periods after stopping depo-provera ? can you get pregnant with irregular cycles or wait until there back regular ?

Varies a lot: Irregular menses are common on Depo-Provera provera (medroxyprogesterone) and end at varying intervals once the shot is discontinued. You may get pregnant while still having irregular menses once you are 90 days out from the last Depo-Provera shot. So use condoms or the morning after pill if pregnancy is not desired. It is easier to date a pregnancy if you wait till menses are regular to become pregnant.

Varies: How soon periods get back to normal varies widely. You definitely can get pregnant while your periods are irregular. The problem is that it is harder to date your pregnancy or know that you might be pregnant. Any time you might get pregnant be sure you are on prenatal vitamins to decrease the risk of birth defects.
