TMI WARNING! ⚠️ Is this discharge normal?

I’m 38w2d FTM, I’m aware that the amount discharge increases substantially as your due date approaches. But I’ve already changed my underwear once today just from being full of discharge (2x as much as this picture) I just wanted to know if everyone else has this much and if it’s normal to be this white when it dries? I am currently 3 days into an antibiotic for a vaginal infection but also taking a probiotic so this is definitely not a yeast infection. It doesn’t smell or itch.
