However there is a supposed two week window in which
Depo-
Provera is supposed to be effective
and that window ended October 8th, so just a few weeks ago. However, I got back on birth control 4 days after this two week window ended on October 12th. The doctor advised me to use a condom in the first week and I go ahead like an airhead and have sex that SAME day, unprotected. While my fiance used the 'pull-out' ' method knowing basic biology, it is still possible to get pregnant.
