TMI! Spotting or period? Opinions please!

Priming for FET and I just came off birth control on Saturday. My clinic told me to call when I started my period to schedule transfer date. Today I had some reddish bleeding but I’m worried they won’t consider it as a period because it’s so light?

I know this is tmi but would you consider this to spotting or bleeding? Bottom pic is this morning & second is around lunch time. I always get breakthrough bleeding on birth control so I’m confused on what to consider this? Period or breakthrough bleeding? I can’t imagine it would be breakthrough bleeding considering I’ve stopped birth control?
