I have been receiving the birth control Depo-Provera since the end of January, 2016. However, I was due for an appointment September 24th, 2016. 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. Its been maybe about 10 days since this happened and while i have really none of the early signs of pregnancy, I'm still worried. Can I get some input?
