If you want to get pregnant but you have been on birth control for 4 mths., when can you try to have a baby?”
Most women will ovulate within two to six weeks after stopping a daily birth control pill, and pregnancies that happen soon after the pill was stopped appear to be on average just as healthy as any other pregnancy, which is a big advantage of the birth control pill– if you decide you want to go off and try to have a baby you can start at any time. The hormones will be out of your body within 24-48 hours, depending on your metabolism.
After you stop the pill you may have irregular periods for a month or two, though, which can make it hard to tell when you are fertile and a little harder to figure out a baby’s due date should you conceive.
If you are not trying hard to not get pregnant, be sure to get enough folate (aka vitamin B9), which helps prevent birth defects– take a supplement that contains at least 600 mcg., and try to get another 1,000 mcg. through foods like lentils, fruit and leafy greens.
