When you are 50 days pregnant, you should not have intercourse, because the fetus is not yet stable at this time. If you have intercourse blindly, first of all, it will cause a preterm miscarriage or bleeding. Therefore, for the sake of the health and stability of the fetus, you should refrain from having intercourse until after 3 months. Also, when you are 50 days pregnant, you should pay attention to your personal hygiene and wash your vulva every day, because after pregnancy, especially due to the constant increase in hormone levels, vaginitis may also occur at this time. Even if you have intercourse after 3 months, you should be as gentle as possible and wash the genitals of both partners to avoid cross-infection. Because most pregnant women are more prone to vaginitis when they have intercourse, they should not have intercourse after 8 months of age to avoid preterm labor.
