Has anyone had impetigo?

Long story short, I’ve had a pregnancy rash that leaves me with sores and have been told to watch for symptoms of impetigo.

Well I got a sore on my bellybutton despite not really scratching that at all and it’s been there about a week now.

It’s not oozing, it sometimes burns but mostly itches, kind of an angry red with yellow crust.

My appointment is not until 7/2 so I’ve been trying to wait for that but I’m constantly aware it’s there and nothing soothes it. Just not sure if there is something wrong or if it’s like this because of the stretching, it’s the only sore on my tummy, the rest are on my arms and legs.

If you’ve had impetigo, did it look/feel like this? Should I get in sooner or just keep using the antimicrobial/antifungal on it until then?

(The red marks are because I scratched to the side of it right before the photo, not spreading infection)

Thanks in advance 🥰
