Any advice? (TMI)

This is my first month TTC #1. I'm 26 and have been on birth control for a little under 6 yrs. I should have ovulated between April 30th-May 4th. Due to the fact that I haven't had a period since coming off the pill I believe AF should show up between Wednesday and Saturday. This morning while checking my CM I had a little bit of bright red blood. AF usually shows within hours of blood when on the pill previously. It has been almost 24 hours, no AF and the color of the blood is way lighter than usual. Any suggestions? Not sure when to start testing. Trying not to be too hopeful. Thanks!
