PP periods

I’m legit going nuts. My periods keep getting worse. They used to be pretty consistent. Day 1 is the worst, and by day 4/5 it’s done. But now they’re all over the place. I’m day 3 and I haven’t gotten off the couch all day. That’s 3 days of not doing anything. Cramps, moody the whole 9 yards. And the amount of blood is so much worse than it used to be. My poor family. I tried BC in college to help with my periods but it made everything worse. Anyone have any suggestions? I’m really sick of being like this.
