TMI - does this look like early pregnancy discharge?

Does this look like I’m about to start my period or does this look like early pregnancy discharge? My period is supposed to start tomorrow, but I’m not cramping like I normally do.

I have a 16 month old and remember my discharge being yellowish with her. It’s been a while since I was pregnant!

We’re not trying but we were pulling out unprotected!

I had a negative pregnancy test strip this morning.
