The pregnancy test is most accurate when the test is taken during the first urination in the morning, because this is the time when the level of human chorionic gonadotropin in the urine is the highest and therefore the detection rate is the highest. Human chorionic gonadotropin is a glycoprotein hormone synthesized by syncytial trophoblast cells, which grows rapidly in early pregnancy and is secreted in greatest amounts by 8-10 weeks of gestation. Its main role is to maintain the luteal lifespan of menstruation, stimulate the production of progesterone and stimulate the secretion of testosterone by the fetus, which is usually self-measured about a week after menopause. In the case of normal women of childbearing age with regular menstruation, the possibility of pregnancy needs to be considered more than one week after menopause, so you can test yourself or go to the hospital for examination to clarify whether you are pregnant.
