A biochemical pregnancy is a miscarriage, but there is no damage to the body, and the body does not react abnormally. A biochemical pregnancy is a miscarriage that occurs when chorionic gonadotropin is elevated during a blood test or when a urine pregnancy test is weakly positive, but after a few days the chorionic gonadotropin in the blood comes down to normal and the urine is negative, which is called a biochemical pregnancy. This type of miscarriage does not affect the lining of the uterus or the body and can be disregarded as a pregnancy calculation. If you want to prepare for pregnancy, you can continue to prepare for pregnancy after the next period is clean. Most people do not feel the biochemical pregnancy miscarriage, and only a small number of people find it when checking the body.
