Planned parenthood cost, is it correct?

I went to planned parenthood today because I thought I had a yeast infection. So they swabbed and then looked under a microscope to check if I did and she said that the amount I have is not even that bad and that it may go away with my period because I'm on it right now. She gave me 2 prescriptions that she said its up to me to get them or not. I went to the front to pay and I was thinking maybe $20 most for the visit being they barely did anything and it came out negative to boot. The lady looks and me and goes okay $81. I almost passed out, I asked to go to the atm. I just cried in my car thinking why the hell did I come here I'm so dumb. Can it seriosuly cost $81 to get checked for a yeast infection? When I get BC it is cheaper than that.
