Eight days after intercourse during the ovulation period, I found that I had backache. Although I had experienced similar symptoms before, I was never sure if this was normal. Later, I consulted a doctor and learned that this might be the result of intercourse during ovulation.

Having sex during ovulation is one of the important ways to get pregnant because sperm can survive in a woman's body for a period of time until implantation. However, if the woman does not have sexual intercourse during this period, the sperm will die and cannot form a fertilized egg.

Backache may be caused by a variety of factors. For example, a woman may experience pain during intercourse or discomfort when the fertilized egg implants. However, if a woman experiences backache after sexual intercourse and it lasts for a long time, it is recommended that she consult a doctor as soon as possible.

The doctor may examine a woman's abdomen and waist to determine if there is an infection or other problem. In addition, doctors may also recommend that women take certain measures after sexual intercourse to prevent the fertilized egg from implanting in the egg. For example, women can take a tablet of folic acid to prevent fetal neural tube defects caused by folic acid deficiency.
