After the secretion of chorionic gonadotropin, it first appears in the blood and then in the urine along with the circulatory system. However, due to its small amount, it is difficult to detect at the beginning and becomes increasingly apparent only after 1-2 weeks of pregnancy. In addition, there may be reactions after pregnancy. So, how long does it take for reactions to occur during pregnancy?
Women may experience pregnancy symptoms around six weeks of pregnancy, such as delayed menstruation, sustained increase in basal body temperature, nausea and vomiting, frequent urination, breast and skin changes, etc. These early pregnancy symptoms usually last until three months of pregnancy. But not everyone will have a reaction in the early stages of pregnancy. If women suspect that they are pregnant, they can use tools such as pregnancy test sticks and test strips to self test. It is best to go to the hospital for examination, as the results are more accurate.
It should be noted that there are significant differences in pregnancy reactions among different groups of people, and it is not scientific to determine whether one is pregnant solely based on symptoms that appear during the early stages of pregnancy. The above physical changes in women are likely caused by factors such as diseases and changes in the internal environment, and may not necessarily be due to pregnancy.
Women must go to the hospital for HCG urine test, HCG blood test, ultrasound and other examinations in order to accurately determine whether they are pregnant and make correct decisions. After delaying the menstrual cycle by 7 days or having sexual intercourse for 10 to 14 days, or as early as 33 days after menopause, it can be used. If early pregnancy testing cannot determine pregnancy, another test can be done around 37 days after menopause.
