What's going on?

With it being the weekend, I can't go to the doctor but I'm stressing out. The past couple of months, I've been dealing with vaginal infections. I have taken antibiotics and have been told everything is cleared up a couple of times but it's back again. I have no idea what's going on. I felt like it could possibly be my menstrual cup because I only seem to have issues after I've used my cup. I thought it was a latex allergy so my boyfriend and I switched to skyn condoms. But tonight, we were having sex and I have to tell him to stop because my vagina was hurting so bad. I've been burning, sweating, and experiencing a weird smell (not like with BV). Any ideas?
