It is normal for a woman to go several months without getting pregnant after a miscarriage, and it is abnormal for her to go more than a year without getting pregnant. It is normal for women not to get pregnant for several months after a miscarriage, mainly because some women do not return to normal ovulation after a miscarriage. Women are most likely to get pregnant when they have sex during ovulation, but there is only one ovulation per month, and not all of them will have sex during ovulation, even if they have sex during ovulation, the sperm and the egg may not necessarily be absolutely combined, coupled with the emotional factors or fatigue, bad habits and other factors that may affect the pregnancy, so trying to conceive for a few months without getting pregnant is normal. However, if you have not been using contraception for more than a year after the miscarriage and have not gotten pregnant naturally, it is abnormal. It may be caused by the miscarriage of the uterine lining damage or tubal failure, ovulation abnormalities, as well as the male sperm quality is not good, etc., need to go to the hospital in time to do infertility examination, for the specific causes of non-pregnancy and then symptomatic treatment.
