The recommendation that women who experience a miscarriage should wait at least six months before getting pregnant appears to be incorrect and needs to be reviewed, conclude Scottish researchers in the British Medical Journal.
The study notes that women who experience a miscarriage are not only at an increased risk of a second miscarriage, but also of complications in a subsequent pregnancy. But the length of time couples should wait before trying again to get pregnant are not consistent, say the researchers.
Delaying getting pregnant is particularly problematic in the western world, the researchers add, because "women over 35 are more likely to experience difficulties in conceiving and women aged 40 years have a 30 percent chance of miscarriage which rises to 50 percent in those aged 45 years or more... any delay in attempting conception could further decrease their chance of a healthy baby."
The researchers reviewed the data of over 30,000 women who attended Scottish hospitals between 1981 and 2000. The results show that women who conceived again within six months were less likely to have another miscarriage, termination of pregnancy or ectopic pregnancy compared to women who got pregnant between six and 12 months after their initial miscarriage. "Our research shows that it is unnecessary for women to delay conception after a miscarriage," concludes lead researcher Sohinee Bhattacharya, from the University of Aberdeen.
