All perfect praise be to Allah, The Lord of The Worlds, and may His peace and blessings be upon our Prophet Muhammad and upon all of his family and companions.
The blood discharged of a woman`s womb indicates that she is in menses regardless of its color. This is so long as it continued for no less than 24 hours and no more than 15 days, and whether the bright-colored blood was discharged before or after the dark. Therefore, a woman who had experienced the aforementioned should abide by the rulings of Sharia as to that which is unlawful for a menstruating woman to do. Moreover, she shouldn`t pray during that period, but when the blood ceases, she is permitted to perform prayers. And Allah Knows Best.
