Weird period

My period was super weird... I started on the 16 and ended on the 22.... kinda..... so the first couple of days was heavy and had lots and lots of clots.... the third day or so it was really light, almost non existent.... and the the second to last day I didn’t wear anything and I only bled when I wiped, and the yesterday was kinda spotting.... well did good no bleeding today until just now when I wipe.... I’ve no clue why or what’s going on. I go to my obgyn on Monday, and I do have severe endometriosis.... so idk... anyone else have this happen?
