Eighty to 90 percent of women who've had one miscarriage go on to have a successful pregnancy the next time they conceive. Even after two miscarriages, the percentage is still 75 [source: Brody]. Those are some good, high numbers -- and good news for a woman hoping to conceive again.
Doctors have long advised women to "wait awhile" before trying for another baby, but a study out of Scotland has proven this conventional wisdom wrong. Researchers analyzed the records of almost 31,000 women who had a miscarriage and then went on to have a second pregnancy. Their findings showed that an interval of less than six months between the two events yielded the best outcomes -- women were less likely to miscarry or have an ectopic pregnancy. Babies were less likely to be born prematurely or require a C-section delivery and were also less likely to have a low birth weight [source: Hollander].
This doesn't mean that a woman must conceive in less than six months after a miscarriage to have a healthy baby -- the study was limited in some ways (for example, was the second pregnancy planned?) and can't be used to answer the question of when's the best time to try again.
What it does mean is that a woman doesn't need to wait to conceive if she doesn't want to, and as soon as she's decided she's emotionally ready, her health care provider should support her decision.
Of course, it's common for an expectant mother who's already miscarried to be more anxious with her second pregnancy. Some women even feel it harder to bond with the baby once he or she is born -- the fear of potential loss puts them on their guard.
Trying again after a loss is scary -- there is the risk, however small, of another loss. But if the possibility of a healthy, happy baby trumps that risk, then perhaps it's time to begin hoping again.
