First time, help

I believe I just had my first chemical. I’ve had lighter positives since November 2 but the line was just always staying the same. I woke up today bleeding. So I’m thinking maybe it’s my period. I have 2 kids so this is my first experience with this. I’m going to call my dr on Monday but would this be considered day 1 of my period? Can we try again this cycle? Any info/advice would be super helpful. Thank you ❤️
