If i had sex 6 days after i missed my depo-provera shot can i get pregnant?

Not likely, but...: Depoprovera works by blocking the release of pituitary gonadotropin hormones that normally keep menstrual cycles regular. Once the depo's blocking is removed, the normal ovulation cycle should resume (but it's not predictable exactly when). Experts on healthtap have mentioned 9-18 months as the time range. A urine pregnancy test done 3 weeks after ovulation can usually tell if there's a pregnancy.
