No wait needed for pregnancy after miscarriage
For the best pregnancy outcomes, when should a woman try to conceive again after a miscarriage? The sooner the better, a new study suggests. Scottish researchers looked at data for nearly 31,000 women who became pregnant after an initial miscarriage. Compared to women who conceived 6 to 12 months after their miscarriage, those who became pregnant again within 6 months were 34% less likely to miscarry a second time. They were also less likely to have an ectopic pregnancy, a cesarean or preterm delivery, or a low-birth-weight infant. The highest risks of a second miscarriage and other pregnancy complications were seen among women who conceived more than 24 months after miscarriage. The findings run contrary to current guidelines by the World Health Organization to wait at least half a year to conceive after having a miscarriage, which affects approximately one in five pregnancies.
