Symptoms of pregnancy during the first week

The first week of pregnancy has the following physiological symptoms: menstrual changes: menstrual cessation is the first sign of pregnancy. All sexually active women should remember the menstrual time. In general, if a month has passed, it should be suspected whether pregnant, and go to the hospital for blood HCG test to determine. Temperature rise: basal temperature refers to the temperature measured in a quiet state, which is also an indicator of pregnancy. In women with normal menstruation, the basal body temperature rises about 0.5°C after ovulation during the menstrual cycle and remains high until the next menstrual period. Due to the influence of progesterone on the body temperature center after pregnancy, the body temperature will continue to remain high. Frequent urination: In the early stages of pregnancy, many pregnant women frequent urination, sometimes once an hour, due to increased bladder pressure on the uterus. After three months of pregnancy, the uterus extends beyond the pelvis and the symptoms disappear naturally.
