A blood test to check for pregnancy will give results in about an hour. Generally, the chemiluminescence method is used to test for elevated chorionic gonadotropin in the blood, and if the blood value exceeds 5 mIU/mL or more, pregnancy is confirmed. The blood test does not require fasting and can be done at any time, which is more sensitive and reliable. Urine test paper to detect pregnancy is not as sensitive as blood, and it is also often inaccurate. If the blood HCG value is less than 5mIU/mL, observe the menstrual condition. If you do not have a period after a week, you should also take another blood test to see if the blood HCG is elevated. If you want to have a baby, do not use drugs indiscriminately during the waiting period to avoid the teratogenic effect of drugs on the fetus.
