T.M.I.... blood color.

I was taking the pill for about 2.5 years I stopped taking it about 5 months ago I had a very short light period within the same month as stopping.

On the 10th of this month a started spotting witch led to my period it's now the 19th and I'm still bleeding!

My period normally would last 5-7 days.

The color seems weird tho it keeps changing from very light pink to bright red to a brownish color.

Can anyone tell me why my period is so long this time and why it's color keeps changing?
