No need to delay pregnancy after miscarriage
You don't need to delay a second pregnancy if you've had a miscarriage, according to Scottish researchers.
In fact, women who got pregnant within six months of their miscarriage were more likely to go on to have a live birth than those who waited longer, the researchers' report shows.
Women are often advised to delay the second pregnancy after a miscarriage. Since 2005, the World Health Organization (WHO) has recommended that women wait at least six months before they try again. To determine the optimum interval between pregnancies, after miscarriage in a first pregnancy, Scottish researchers examined hospital data for 30,937 women who had a miscarriage in their first pregnancy.
Of those who got pregnant within six months of the miscarriage, 85 percent gave birth to a live baby though 10 percent miscarried again. If more time went by, however, fewer than 80 percent of the women had live births and more than 12 percent miscarried. These findings held even after accounting for the women's age and socioeconomic status, although adjusting for smoking tended to reduce the difference.
The results also say nothing about the effects of the 2005 WHO guidelines because the hospital records examined were from 1981 to 2000. If most of the women were trying to get pregnant again right away, those who succeeded early on might have had a healthier reproductive system. That, in turn, might boost their chances of having a live birth.
Nevertheless, the results of the current study indicate that women who conceive within six months of an initial miscarriage have a better pregnancy and lower complication rates in a subsequent pregnancy.
