Many doctors advise all women to wait 18 to 24 months after they've given birth before trying to conceive again, but this is especially true for those who've delivered by c-section. This time-out gives your body a chance to heal and recover from surgery. Research shows that getting pregnant less than six months after a c-section can increase your risk of complications like a ruptured uterus or having a low birth weight baby during your next pregnancy. If you'd like to try for a vaginal birth next time (VBAC), you have even more reason to consider holding off on getting pregnant, since studies have found that the rate of uterine rupture is higher during VBACs when it's been less than two years between deliveries.
Of course, many women who get pregnant again quickly have totally healthy pregnancies and babies. And if you're older than 35, you may not want to wait more than a year or two to have another baby since fertility issues tend to rise with age. If you want to time your pregnancies close together because of your age or for other reasons, talk to your doctor. If you had a healthy pregnancy, it may be quite safe for you to begin trying to conceive again sooner.
