Implantation bleeding?

I have been having light pink bleeding when I wipe since yesterday, but it was only once that I noticed it and then again today. Today I also feel a little crampy but not anything like when I have my period. My ovulation date was the 9th and my period is predicted to start the 23rd. My cycles have always been regular and I’ve never had random spotting before. I have a appointment scheduled with my OB/GYN the 26th to have her check everything. Just wanted some advice/opinions before I go.
