Question: how long do you have to be off of birth control pills to get pregnant?
Answer: You may be able to get pregnant within 1-3 months of stopping a combination pill -- meaning those that have estrogen and progestin. But most women can get pregnant within a year. One study even found that women who took the pill for more than 4 or 5 years were more fertile than those who used it for 2 years or less.
