It is not normal to bleed bright red after sex while about 4 weeks pregnant.

Bright red bleeding during pregnancy can be a sign of serious complications such as a miscarriage, ectopic pregnancy or placenta previa.

You should seek immediate medical attention if you experience any vaginal bleeding during pregnancy, especially if it is bright red, heavy, or accompanied by other symptoms such as abdominal pain, fever, or dizziness.

Your healthcare provider will perform a physical exam, check your medical history, and may order tests, such as an ultrasound, to determine the cause of the bleeding and assess the health of the pregnancy.

Waiting to seek medical attention could put your pregnancy at risk, so it is important to act promptly if you experience any abnormal bleeding.
