Changes from the pill

Sa

So ive been on the pill for several months now, and my period has been consistent, but also inconsistent. I get it at the same time each month of course, but the way i bleed is different almost every time. Sometimes i will have just brown spotting for the first day all day then it will randomly pick up to dark red, very strange looking blood that feels heavy, but really isnt that much. Other times it will come full force. But a lot of time im just spotting light pink and brown. But when i do bleed, the blood is a super weird color. Like nothing i had with my natural periods. Anyone else have this? I had pretty consistent periods before the pill. Bled consistently for three days and lightly bled and spotted for the last two and it was the typical bright red blood. Sorry thats confusing but i find how its constantly changing is weird
