My period is about two months late, had my last real period June 1st. Took negative pregnancy tests so I’m not pregnant.

Starting a few days ago I started to have some brown discharge which is normal so I figured my period was finally coming and that hopefully my cycle would regulate. Now it’s probably the fourth day since and those few days I’ve been having a lot of the bloody discharge (TMI) with a lot of dark clots and such. What do you guys think, do you think this is my actual period? Or maybe my uterus is just expelling everything after not having a period for so long? 😂 Or could this be something of concern? This has never happened to me but then again having such a late period wasn’t normal for me either.
