Sudden desire does not necessarily mean that you are pregnant. There is no direct relationship between pregnancy and sex drive. Sudden desire only means that one’s libido has increased and the level of hormones in the body has increased, but it is not a reaction to pregnancy, so it does not mean that the increase in libido is a sign of pregnancy. To determine whether a woman is pregnant, there are two prerequisites to consider: first, having sex without the protection of safety measures and ejaculation, and second, the woman’s menstrual period is delayed or stopped. At this time, you can use a pregnancy test or go to the hospital for a blood test Hcg to determine whether you are pregnant or not.
