I am often asked by my patients 'How long should I wait after experiencing an early pregnancy loss or miscarriage before getting pregnant again?'
These questions usually have several different components. One is, when does fertility begin after a miscarriage, and the other is when it is safe to get pregnant again after a miscarriage.
Before I answer these questions, it is important for couples to understand what a miscarriage, specifically an early miscarriage is. An early pregnancy loss or miscarriage happens usually during the first 8-12 weeks of the pregnancy, but some physicians extend this period up to 20 weeks.
Fertility equals ovulation, and ovulation can be expected within 4-6 weeks after a pregnancy loss, though it can occur as early as 2 weeks after the loss. Fertility, therefore, begins as early as 2 weeks after a loss.
In the past, doctors suggested for patients to wait at least 3 months after an early pregnancy loss before trying to conceive and get pregnant. But recent studies have confirmed that women who wait 3 months or less after a loss had higher live birth rates when compared to women who waited longer, notably if the wait was over 12 months then fecundability decreased significantly when compared to waiting 0-3 or 3-6 months.
So there is the answer. After an early pregnancy loss or miscarriage, you should try and get pregnant within 3 months to improve your chances of having a live birth.
