Thrush?

I just noticed earlier that my nipples were really red. When I touched them, they kind of burned and are a little itchy. My son is 8 weeks old and has been EBF since birth. He has no signs of thrush at all. I have an obgyn appointment on Tuesday and he has his 2 month appointment Wednesday. Is it okay to wait until then or should I go into urgent care tomorrow for treatment? I’m not sure if it is thrush but based on my symptoms it sounds like it.

Is there anything I can do until Tuesday to treat it or subdue the symptoms or rule thrush out?
