How big a pregnant woman’s belly is in the third trimester of pregnancy is something that needs to be determined based on whether it is a single or multiple birth and cannot be generalized. If there is only a single fetus, the belly bulge will not be very obvious; if it is a multiple fetus, you may see a slight bulge in the belly. The vast majority of women with a single pregnancy, 3 months pregnant, the uterus has just come out of the pelvis, the uterine fundus is at most 1 to 2 fingers above the pubic symphysis, so the uterus can generally be carefully touched to feel the enlargement of the lower abdomen, the abdomen may not be noticeable bulging. In the case of a twin pregnancy, the enlarged uterus can be felt between the umbilicus and the pubic symphysis. The third trimester of pregnancy should be to the hospital on time for maternity checkups, usually pay attention to more rest, moderate exercise, if there is any discomfort, should immediately go to the hospital.
