Periods on the pill

Chelsea • 🤰🏼🤱🏽💕
I finished my first pill packet last Thursday and I got my period on the Sunday or Monday I believe..the first day was heavy but half the pain I normally get which is great! But day four and I'm still bleeding but it's only a tiny bit and I feel like I'm wasting tampons because throughout a whole day it will only fill the tip of the tampon..I'm just wondering, when I start my second pill packet tonight, will my period stop by tomorrow or Saturday? Or will I bleed until my body needs to? Just wondering if I really need to waste any more tampons or if I should just use panty liners until I stop bleeding
