Vaginal Infection 2 Days Post Sex ??

Im not sure whether this is a Yeast Infection or something serious. It feels very itchy and kind of annoying more than painful. I tried to insert my finger into my vagina and see if I could look at my discharge and it really hurt. I had sex with my boyfriend on Monday and we did use a new condom but Im not sure if it was the brand or him that is making me irritate. I also read that it could be due to uncleanliness but Im not sure. Im really scared to talk to my mom only because I feel like she will relate it to me having sex and will yell at me. I want to go to the doctors but even “free” clinics require like a $100+ fee for pelvic exams. Help😩😩.
