In general, having sex in the first trimester has an impact on the fetus. It is suggested that pregnant women who feel unwell in the first trimester should seek medical treatment in time, and standardized treatment under the guidance of a doctor will help them recover. The specific analysis is as follows:
In the early pregnancy, because the implantation of fertilized eggs is not very firm, the development of embryos is not yet fully mature. If pregnant women have sex at this time, it may cause endometrial excitement, which may lead to threatened abortion or even abortion, so having sex in the first trimester has an impact on the fetus. Moreover, having sex in the first trimester may also bring bacteria into the vagina, thus causing infection. Maternal infection may cause harm to the fetus, such as fetal malformation and premature delivery. Having sex in the first trimester may also make pregnant women overtired and emotional, and these factors may also have adverse effects on the normal development of the fetus, so it is suggested that pregnant women should not have sex in the first trimester.
Pregnant women should diversify their diet in their daily life, so that the nutrition in the body is balanced, and they can also exercise moderately to improve their physical fitness, which is beneficial to the health of themselves and their fetuses.
