Bleeding

An

Hi! I am 6months PP and have yet to get a period. I had a positive OPK ON 5/16 and 5/17. Had sex on 5/17. Yesterday I started bleeding and also today. It’s not a ton of bleeding. Not enough for a tampon but just enough for a thin pad.

Is it possible this is my period?? It seems too close after the positive OPKs, but I feel like my body may be a little off still? Implantation bleeding maybe? What do you guys think?

Also I’m almost positive I ovulated during those OPKs because I was have EW CM and was bloated, and my uterus was unwell, along with uncomfortable sex
