Having sex and ejaculating inside the body on the 5th day after the cleansing operation is not very likely to be pregnant, but it is very harmful to the body and it is better not to have sex at this time. 5 days after the induction and removal of the uterus, the endometrium has not yet fully recovered and the possibility of fertilized egg implantation is relatively small, so you can not worry too much about the risk of unwanted pregnancy. However, because the endometrial damage has not yet recovered, intercourse at this time is likely to cause uterine cavity infection, so it is best to prohibit sexual life for 1 month after the cleansing operation.
