Uuuuggghhhh....Am I freaking out for no reason??

I am super paranoid about ANYTHING that looks like spotting, since that was the only sign I had of my missed MC a few months ago before this pregnancy...been getting discharge like this tonight. I know it’s not hardly anything, but it makes me soooo nervous because it wasn’t a lot last time either. Anyone else having anything like this? Just needing some peace of mind 😩 I feel like there’s literally nothing I can do except wait for my ultrasound in 3 weeks.
