If libido increases during pregnancy, it is because both estrogen and progesterone in the body increase, so it will make libido increase. If a woman enters menopause, ovarian function declines, estrogen secretion decreases, and her sex drive decreases significantly, so if the sex drive increases during pregnancy, it is related to the hormone level secretion in the body. But in the first three months and the second three months of pregnancy can not have sex, because the first three months of the embryo is not yet stable, once have sex is likely to cause miscarriage phenomenon, the second three months may also cause premature labor phenomenon, so before and after three months can not have sex. If you have sex in the middle of pregnancy, it is recommended to reduce the frequency of sex, and sex action can not be rough, so as not to stimulate the adverse consequences. So if you have an increased sex drive during pregnancy, it is best to sleep in separate beds with your husband to avoid skin-to-skin contact, which can reduce your sex drive and the number of times you have sex.
