Implantation spotting?

Had a chemical end of April/beginning of May. Had a period May 27-31, and I think I ovulated early based on egg white cm and tender breasts (my normal ovulation symptoms). That started June 1. I had very light pink/brown spotting yesterday only when I wiped. Also had cramping and still have a little bit of cramping and increased cm that isn’t egg white, just wet. I’ve messaged my OB and she says it could be implantation bleeding. Just seeing if anything similar has happened to anyone else?
