My period wont stop for 13 days now , its almost dark blood and heavy , ps : pink spots in the first days ?

Menorrhagia: Hi, having a period for 13 days is not normal or fun, the first thing comes to the mind in a young sexually active woman is a retained tissue after a miscarriage, therefore you need medical attention, if not sexually active then infection, structural abnormality and hormonal imbalanced and thyroid problems among other thing r other possibilities. In any case you need medical attention ASAP.
