Pregnant women’s orgasms have an effect on the fetus because they can cause contractions in the uterus, which can lead to miscarriage. Orgasm will stimulate the body to produce a large amount of estrogen, which has an impact on the stability of the fetus, especially in early and late pregnancy, because it is easy to miscarriage and premature birth, so pay attention to control the sexual desire during these two periods and avoid excessive sexual stimulation. Pay attention to rest and exercise during pregnancy to help the growth and development of the fetus and to eliminate the discomfort that pregnancy brings to women. Pay attention to observe if any physical discomfort appears. Pay attention to prenatal checkups on time to understand the development of the fetus, so that problems can be solved in time. During pregnancy, local infections can easily occur, so pay attention to keep the perineum clean and hygienic, and change underwear regularly, which can effectively reduce the incidence of infection.
