Implantation bleeding or period?

I’ve been ttc for about a month now. So according to my charting my period should have started about 4 days ago, but I’m about 10-14 days past ovulation is this implantation bleeding? Warning TMI coming your way... it was very light pinkish and only when I wipe do I see it, no cramping like before a normal period would start. What’s been your experience with this? I’d like some advice on when to take a test. 🤔🤞🏻🤰🏻
