If you got your period for few days and then you saw your purity which tells you that your period is over, take ghusul and fast and pray. If you see after that colored discharges, ignore them! But if you see the flow of the blood again, you must stop until the total of the first period and the second reaches 15 days in a month. Then you can consider this blood that exceeds 15 days to be irregular bleeding and you can fast and pray.

I am having weird menses pattern- periods last for more than 7 days since a while now (after my second child) but it’s not bleeding, it’s just spotting from 4-5th day onwards I fasted & prayed yesterday when I didn’t see any discharge for more than half day, & today also I’m fasting, but just now I saw blood in the discharge So is my fast valid for today & yesterday or I need to make them up?
