WERID DISCHARGE?? sos help TMIII warningggg

Sorry tmi for pic, I've been having really weird and abnormal I think discharge recently. My vag is red inside (no bumbs or anything like that). Has no bumps but is itchy and and swollen but I can't tell if it's itchy from hair growing back or swollen from sex. Also it was burning alittle but not much really when I pee like once or twice but again it was burning ish from the wax. Background at first I thought it was cause I had a really bad Brazilian wax (cause I had gotten it done right when I was about to get my period, i didn't know and I was really sensitive and also didn't exfoliate enough) and than I had a lot of sex with my bf. So idk if it's cause of the wax which my vag is still all irrated and because I kept having sex (which didn't help). It got so irrated that it hurts when my bf try's to slid it in but I also think it's cause we had rough sex a couple days ago. Does anyone think I have a yeast infection or any other infection? Any tips? Or in store products or Home remedies? Anything? I'm 17 and I want too avoid the gyn if I can. Anyone?? Plz
