Whyyyy

So about 4 years ago I was on the depo shot and that caused me to have my period for over 200 days and it was the most miserable time in my life. I recently just got on the pill, I’m getting towards the end of my third pack, and up until now my periods have been completely normal. My periods are normally 6 days and I’m now on the 7th day, which isn’t a big deal, 1 extra day is fine. But I’m terrified of the same happening when I was on the depo shot. I just don’t know what to do. pregnancy prevention wasn’t even the reason I got on the pill, it was to clear my acne and I’m now breaking out.. so I’m wondering if it would be wise to stop taking it or if that would cause even more issues? I would love some advice ❤️
