Has this happened to anyone before?

I’m currently on day 29 of my cycle (my cycles are normally 26-27 days) Two days ago I had a small gush of blood just when I wiped and then nothing after (bright red with even a slight clot) now two days later and still nothing except very light brown discharge just when I wipe… normally when my periods start it’s the opposite, I have spotting them a large flow.

Has anyone had a small gush like that and it be implantation bleeding? I’ll test tomorrow morning just curious if any ones had this happen before.
