Understanding a women’s body 😒😭

I have been irregular for years can go months without a period. This past year they’ve been coming more frequently like less months in between. Anyways, I had a 9 day period (very HEAVY one) from 7/8 - 7/16 and I had spotting/blood spells 7/31 - 8/3 nothing ever stained my pad just when I’d wipe randomly sometimes it was there sometimes not, started pink then brown then a little red then a little pink and now nothing. Anyone have any ideas what could be happening? Monday I had to very bad dizzy spells not saying it’s related but who knows. Lol
