Generally, it is possible to have intercourse in the fourth to sixth month of pregnancy, but there are some special circumstances that do not recommend coitus, such as early pregnancy, late pregnancy, vaginal bleeding, and so on. At 4~6 months of pregnancy, the placenta is better developed, the fetus begins to form and develop stably, and it is relatively safe to have intercourse at this time. If there is no gonorrhea, AIDS, etc., as well as other complications in the low-risk period of pregnant women can moderate coitus. However, the first three months of pregnancy, due to the hormone level fluctuations in the pregnant woman’s body, the embryo is unstable, this stage is not recommended coitus, easy to lead to miscarriage. In the late stages of pregnancy as the fetus slowly increases in size and begins to approach the mouth of the uterus, coitus may cause the child to experience premature labor. In addition, if a woman during pregnancy, there is abnormal vaginal bleeding, it may be preeclampsia, placental abruption, etc., at this time you can not cohabit, so as not to aggravate the bleeding situation, and even lead to miscarriage. During pregnancy, coitus should be gentle, at the same time to strengthen the nutrition, eat more fresh fruits and vegetables and milk, pay attention to rest, early pregnancy can take some folic acid tablets, follow the doctor’s advice to do regular pregnancy checkups. If you have any discomfort during pregnancy, we recommend that you go to the hospital in time and follow the doctor’s instructions.
