Generally speaking, pregnancy testing can be done about ten days after pregnancy, because at this time the body will produce a hormone called human chorionic gonadotropin (HCG), which is a sign of pregnancy. When testing, women can buy pregnancy test strips in pharmacies or go to the hospital for a serum HCG test. However, it should be noted that the shorter the pregnancy, the less accurate the test results will be. Therefore, it is recommended that women wait at least two weeks after pregnancy to have another check-up to get more accurate information.
