One month after a miscarriage, you can get pregnant by having intercourse. In about 40% of women, ovulation resumes half a month after a miscarriage, so having sex after a miscarriage can lead to pregnancy. Of course a month after a miscarriage, not during ovulation, the chances of getting pregnant may be much lower. A woman’s ovulation is affected by many factors. Emotional tension, too much pressure from work or study or changes in the environment can affect ovulation. That is why it is important to use contraception whenever you have sex after an abortion. The best method of contraception is to use a condom, which on the one hand can contracept; on the other hand, it can also prevent bacterial infection.
