Eight days after having sex during ovulation, you may experience a series of physical and psychological changes. These changes may make you feel uncomfortable or sore, but they are also signs that your body is preparing for childbirth. If you are experiencing backache, you may be in a different stage of pregnancy.

If you feel backache 8 days after intercourse during ovulation, you can consider the following points:

1. You may be in the early stages of pregnancy. If you have sex during the ovulation period and feel backache 8 days later, this may be one of the symptoms of early pregnancy.

2. Pay attention to personal hygiene. If you experience backache, you should pay attention to personal hygiene to avoid infection with bacteria and viruses. This can help reduce your risk of infection and help ensure good health.

3. Consult a doctor. If your backache lasts for a long time or is accompanied by other symptoms such as vomiting, nausea, headache, etc., then you should consult your doctor. Your doctor can help you determine the likelihood of pregnancy and develop an appropriate treatment plan.

If you have sex during the ovulation period and feel backache 8 days later, this may be one of the symptoms of early pregnancy. If you are unsure whether you are pregnant or have other symptoms, talk to your doctor.
