Help !!

For a couple days my vaginal lips have been INSANELY itchy and irritated. I had a really thick white discharge but then I started my period. It was super irritated right after I had sex. I’m not sure if it was from friction from our sex position or if I have a yeast infection. It could even be from shaving. I’ve had only one partner and I’m still with him. He said he didn’t have anything. I’m really worried. Should I be?


I’ve been looking stuff up on google and I saw where antibiotics can cause yeast infections. I’ve been on antibiotics since July for my acne. Could that be it??
