HELP!! ⚠️⚠️

My period has been normal, and fairly predictable. It lasts 7 days and is relatively heavy. All of a sudden, and out of the blue, it's been abnormal...

I started much later than normal, by roughly 4-5 days. I thought nothing of it, as the flow was the usual (I was supposed to start 5/27.)

I figured, okay, I'll just take a test once my ovulating time frame is done, but two weeks later, I started my period again...

It started how a period ends, little, with brownish/red discharge, for a day or two before it finally bled like normal.

My current period is scaring me, I started as normal, but it was supposed to end on 7/20... there's still that reddish brown discharge, but sometimes blood comes out, the texture is off, somewhat mucusy, and I'm getting a little bit of cramps here and there...

What the hell is going on?

I can't take a test, every time I try to, my period comes up...
