Trying to Conceive After Miscarriage

Recent research from NIH suggests that women who try to conceive within three months of an early miscarriage can conceive as quick or more quickly than women who wait for three or more months. The data showed a 69% pregnancy rate for women who tried sooner, versus a 51% pregnancy rate for those who waited longer than three months. And the live birth rate was 53% for women who tried sooner, versus 36% for those who waited.

It may be that changes in the uterus related to an early pregnancy – increased blood flow, presence of growth factors –help the body be prepared for another pregnancy sooner, rather than having any detrimental effect, explains Dr. John Rapisarda, a fertility doctor and managing partner at Fertility Centers of Illinois (FCI).

“One of the concerns people may have had, related to waiting for a period of time, is the risk of the uterus not going back to normal, and there being inflammation or some kind of repair that needs to take place before somebody tries again. But I think that the uterus is a very forgiving organ. It is used to rejuvenating itself on a monthly basis and recovers very quickly from an early pregnancy,” he adds.

Other than emotional reasons there probably aren’t physical reasons why a couple needs to wait, says Rapisarda, who leads FCI’s Center for Recurrent Pregnancy Loss.

“Following a miscarriage, whether it’s with a D and C or it occurs spontaneously, the pregnancy hormone (HCG level) should fall rapidly to zero,” he explains. “And if it doesn’t, you get concerned about there being retained tissue. I don’t want [my patients] to be trying and then find out later that there’s a piece of tissue that remained and prevented them from getting pregnant again. Once the HCG level is down to zero and they have a period I’ll let them start trying again.”
