Chest pain during ovulation does not necessarily mean pregnancy. Although chest pain during ovulation is normal in most cases, it does not necessarily mean you are pregnant. In fact, normal fetal buds and heartbeats only occur when you are pregnant.

1. Breast Growth: If you are growing, your breasts may feel sore. This is normal, but if you have pain that lasts a long time, you may want to consider getting a breast exam.

2. Breast infection: If you experience chest pain that is accompanied by warmth, redness, swelling, and pain, you may want to consider getting a breast exam and treatment.

3. Underwear that is too tight: If the underwear you use is too tight, it may put pressure on your breasts and cause pain. You can try changing to looser-fitting underwear.

4. Other illnesses: If your chest pain is accompanied by other symptoms, such as headache, nausea, vomiting, diarrhea, etc., then you may want to consider getting tested and treated.

If you experience chest pain during ovulation, it's a good idea to talk to your doctor first to find out what's causing the pain. If you suspect you are pregnant, you can take a pregnancy test or talk to your doctor. If you are not sure how to test or need more help, you can talk to your doctor or professional medical provider.
