Here's why it's important to seek medical advice:
* Miscarriage: Heavy bleeding with clots and cramping can be a sign of a miscarriage, especially if you knew you were pregnant.
* Ectopic Pregnancy: An ectopic pregnancy (where the fertilized egg implants outside the uterus) can cause bleeding and abdominal pain. This is a medical emergency.
* Hormonal Imbalance: Changes in hormone levels can sometimes lead to irregular or heavy periods.
* Infection: Infections in the reproductive system can also cause bleeding.
* Uterine Fibroids or Polyps: These non-cancerous growths in the uterus can sometimes cause heavier periods.
* Changes in Contraception: Starting or stopping hormonal birth control can affect your menstrual cycle.
Given the uncertainty and the potential for serious causes, it's essential to contact a healthcare professional, such as your doctor or a gynecologist, as soon as possible. They can evaluate your symptoms, perform necessary tests (like a pregnancy test or ultrasound), and provide an accurate diagnosis and appropriate care.
