I have been on the Depo shot for little over 2 years, I'm due for my shot in 4 days and about 1 1/2 weeks my husband will be home and we want to know if we can have unprotected sex and not get pregnant. If I've beebn on the shot for 2 years will I get pregnant after 2 weeks of my shot. Keep in mind one of my side effects was not mentrual period for the 2 years I was under the shot.
