Frequent urination usually starts around 6 weeks of pregnancy, but it varies from person to person. For example, if someone has an anterior uterus, then frequent urination will occur earlier, and if they have a posterior uterus, frequent urination will occur a little later. Pregnant women can also urinate frequently at the end of pregnancy. The end of pregnancy is mainly due to the fetus gradually falling into the pelvis and pressing on the bladder, leading to frequent urination. In order to control frequent urination, try to drink as little water as possible, especially 1-2 hours before going to bed, to avoid frequent urination at night, which affects the rest of pregnant women.
