You can have intercourse for 1 month after recuperation from a biochemical pregnancy. However, during the recuperation period, you must go back to the hospital for a follow-up ultrasound to determine if the pregnancy is clean. A biochemical pregnancy is a pregnancy in which the sperm and egg meet in the fallopian tube to form a fertilized egg. If the fertilized egg does not enter the uterine cavity for implantation or if implantation fails, it represents a biochemical pregnancy. Since this pregnancy is measurable in the blood, it means that there is a transient increase in hCG. A biochemical pregnancy usually presents as a delayed normal period, so most women may experience a period without realizing they are pregnant. The occurrence of biochemical pregnancy may have a certain cause, so even if intercourse is recommended, temporary contraception is recommended and the patient should preferably go to a regular hospital to check what caused the biochemical pregnancy before getting pregnant. In addition, after a biochemical pregnancy, patients are advised to eat more warm and tonic foods and maintain a healthy and regular lifestyle.
