It is possible to swim when pregnant, but avoid swimming in the early and late stages of pregnancy, as this may easily lead to miscarriage or preterm labor. When swimming, try to choose a swimming place with good hygiene to avoid infectious diseases. Swimming is a better form of exercise for pregnant women, so pregnant women can swim. However, in the early stage of pregnancy, because the embryo is unstable and in a critical period of growth and development, if infected with a virus during swimming, it may have a greater impact on the development of the embryo, so try not to swim in the early stage of pregnancy. Swimming in late pregnancy is also not recommended. Swimming in late pregnancy may lead to infections of the reproductive system, premature rupture of membranes, etc., and is not recommended in late pregnancy. Pregnant women should try to choose a swimming place with good hygiene when swimming, and do not use towels and swimming caps in public areas to avoid infection. Moreover, when pregnant women swim, the range of motion should not be too large, otherwise it may induce preterm miscarriage. If a pregnant woman experiences abdominal pain or vaginal bleeding during swimming, she should stop swimming immediately and go to the hospital in time.
