What should you do if you are 4 months pregnant and during intercourse you start bleeding a lot?

If you are four months pregnant and experience heavy bleeding during intercourse, it's important to stop immediately and seek medical attention. Heavy bleeding can be a sign of complications, such as a miscarriage or placental issues, and requires prompt evaluation by a healthcare professional. Contact your doctor or go to the nearest emergency room to ensure both your health and the health of your baby are assessed. Avoid sexual activity until you have been evaluated and receive guidance from your healthcare provider.
