Back pain and stomach pain during intercourse during ovulation are very common, especially among couples who are preparing to become pregnant. This condition can be caused by a variety of factors, including infection, inflammation, medication side effects, and more.

Some couples may experience lower back and stomach pain, but this does not necessarily mean they are about to become pregnant. If the pain persists or worsens, or is accompanied by other symptoms such as vaginal bleeding or discharge, you may need to seek medical help.

If you are experiencing lower back and stomach pain, here are some suggestions that may help relieve your symptoms:

1. Rest: Getting enough rest can reduce pain.

2. Use hot or cold compresses: Use a hot water bottle or ice pack to relieve pain.

3. Diet: Eat a healthy diet and avoid eating too much greasy or spicy food.

4. Drug treatment: Non-steroidal anti-inflammatory drugs (NSDs) and other drugs can be used to relieve pain.

5. Consult your doctor: If pain persists or worsens, or is accompanied by other symptoms, you should consult your doctor for further help.

For couples who are preparing to conceive, having sex during ovulation can increase the probability of pregnancy. However, if you experience pain in your waist or stomach, you should treat it with caution and consult your doctor for further help.
