What Causes Air Bubbles And White Discharge From Vagina After Unprotected Sex?

Hi, I had an unprotected Threesome on Sunday morning July 23rd, 2011 at about 3AM, then at about 11pm that night had sex again with a different person with a warming sensations condom, and the guy entered me a few times unprotected which I was unaware of until after the fact... On that Monday I started to expierence air bubbles coming from my V, and then the next day clumpy, bright white discharge was coming from from my V with no smell, no pain, no itching, Just feeling uncomfortable... So I'm on day 2 of a 3 day yeast infection kit & still feeling bubbles... What is it? I have appointment with my Doc on August 9th, but I'm going crazy, please help...
