Hello. My vulva is now currently swollen. It has been swollen before, and my right vaginal lip was still swollen but despite this, my partner and I wanted to try intercourse again today. I've also had white, cottage cheese like discharge. Right now it hurts and it is incredibly hard for me to walk. I am very scared. I am also three days late on my period, but I took a pregnancy test and it came out negative. Please help. I am pretty sure I have a yeast infection and was planning on purchasing one of those three day treatments at my local pharmacy. Thankyou for you time. -Carmen
