Ringworm in scalp

I’m 36 weeks pregnant and my daughter came home from school with a bald spot in her head but I thought she had cut her hair out or something so I styled it where you couldn’t see the spot but I still made her a doctors appointment for it to be looked at... well to make a long story short we share the same comb and now I can see a bald spot coming in my head just like hers... what Can I do since I’m pregnant and can’t take the oral medication???
