Hi, Heavy clots during menstruation can be a common occurrence for some women, but they can also indicate an underlying health condition. Here are some possible causes of heavy clotting during menstruation: - Hormonal imbalances: Fluctuations in hormone levels can cause heavy bleeding and clots during menstruation. - Fibroids: Noncancerous growths in the uterus can cause heavy and painful periods. - Endometriosis: A condition where the tissue that lines the uterus grows outside of it, which can cause heavy bleeding, clots, and pain. - Adenomyosis: A condition where the tissue that lines the uterus grows into the uterine walls, which can cause heavy bleeding, cramps, and clotting. - Miscarriage: If you are trying to conceive, heavy bleeding and clotting can also indicate a miscarriage. It s important to speak with your healthcare provider about your symptoms and concerns. If you feel that your current OB/GYN is not addressing your concerns adequately, you can seek a second opinion from another provider. Your provider may recommend further testing, such as an ultrasound or blood tests, to determine the cause of your heavy bleeding and clots. Treatment options will depend on the underlying cause and your situation but can include medications, hormone therapy, or surgery. Take care. Hope I have answered your question.
