Please doctors i didn't get my answer about my last question (what are the causes of giving clotted blood during bleeding period(mensurating))?

Multiple causes: Threatened or spontaneous abortion, hormonal bleeding, infection or inflammation: you questions cannot be answered with words- you must be examined and tested.

Could be incidental: Passing clotted blood during a menstrual period happens to a lot of otherwise healthy women. If you've been sexually active, it could be a very, very early miscarriage. If this happens constantly, you could have one of many clotting disorders/hypercoagulable states like Factor V Leiden (most common), anti-phospholipid antibody syndrome, inflammatory bowel...long list. Might just have been random.
