What is happening?? 🙃

My apps are saying that I started ovulation right after AF this cycle. I was sure I did too because I did have EWCM a day or two later, and some pains in my sides and back. My last AF started on Jan 25 (I am not late yet or anything) but yesterday I had a little bit of pink/orange looking spotting in my underwear. It was only a few drops and then stopped. Is this ovulation bleeding? Or possible implantation? Don't want to get my hopes up too soon.
