Birth control pills or the Nuva Ring have return to fertility within weeks of stopping them. Many women start birth control pills as teenagers, and stop them in their late-30’s when ready to conceive – fertility is the same as for non-Pill users, their age when starting trying to conceive may be a factor rather than the length of time on the pill. Depo-Provera shots can stop periods for 6-18 months after stopping – during this time fertility is low but there are no long-term bad effects.
