Physiological activity should refer to sexual intercourse, which is generally not recommended in early pregnancy.
Early pregnancy is an important stage for the formation of the fertilized egg, the implantation of the embryo, the attachment of the placenta and the rapid development of the embryo. During this period, the fetus has not yet stabilized and the placenta has not yet fully stabilized its attachment. If you have sex in early pregnancy, it may lead to uterine contractions and may even lead to miscarriage and other situations. Therefore, it is not recommended to have sex in early pregnancy.
If you need to have sex, you can have sex between the third and seventh months of pregnancy. Sex at this time will not affect the growth and development of the fetus, but you should pay attention to maintaining the appropriate strength, while avoiding excessive frequent sex, and you should also pay attention to personal hygiene.
During pregnancy, you should go to the hospital regularly for maternity checkups, and if you feel unwell, you need to go to the hospital in time.
