Umm? Help!

Hey guys. So I was supposed to start my period between 6/17-6/18

I started my “period” 6/15.

Previously during that cycle before I started bleeding, I was having ovulation like cramping, and tenderness. I spotted pink twice and then on 6/15 i spotted brown and that night I had regular bleeding. I have ALWAYS had heavy periods with horrible cramping and this month I didn’t. Like. At all.

Today is 6/22 and it’s been exactly a week and I stopped the heavy bleeding on 6/20 and I’ve had bright red spotting up until today and still have had the ovulation cramps the entire time.

I haven’t taken a test because I’m sure it’s negative. But has this happen to anyone?
