Although the WHO recommends waiting about six months to seek pregnancy again, there are numerous studies that indicate that the sooner the pregnancy is resumed, the lower the chances of suffering a new miscarriage or other gestational complications.
The WHO recommendations are based fundamentally on emotional aspects, since miscarriage is a hard trauma and it is convenient to have overcome this grief and be prepared to face the new pregnancy with illusion. On the other hand, the studies that indicate that it is not necessary to wait to conceive again after the abortion are based on physiological aspects of the female body.
In any case, it is important to consult your doctor. Many specialists recommend waiting an average of two menstrual periods before trying again. However, this depends very much on the type of miscarriage that has occurred and the consequences of the miscarriage both physically and emotionally.
