implantation bleeding?

J 🌸💛
Today's CD 23! I had some random light pink discharge today during one bathroom trip (nothing in the AM and nothing afterwards or since then). Wondering if that could be implantation bleeding? I'm not sure when and if I ovulated this month. I ever got a dark positive but I did get one very close negative 🙄 We haven't BDed in a few days. I really wish they could take the guessing out of all this TTC lol it's the year 2000 they should have some scientific crap figured out by now. ✌🏼 I guess my Q is what are some signs of implantation bleeding? I never had any the two times I was pregnant.
