Hello, I Am Concerned About One Small Blood Looking Bump

Hello, I am concerned about one small blood looking bump or blister right under my clitorous on the wall right before the inside of my vagina. I never had this before and noticed something different when I tried to have sex with my boyfriend after the first time. It is extremely painful only if he tries to put himself inside me to where I have to stop and not let him enter. I don't itch or it doesn't burn when I pee so not sure if it would be and std. I might have normal discharge from my vagina once in a while but that's it. I haven't noticed this until I finally wondered what had been going on sense we have been trying to have sex for a week now. I assumed from him gifted in size maybe I was sore the first time so we tried a lube. It did help but still was sore like a sharp pain when he first tried to enter. After that time I seemed to have had some light bleeding that night. Small bump is sore to the touch and I have took a picture to try and take a look of what or if there was anything there for the discription and that's when I emailed you guys. I know you get a lot of things people come to you about but I am embarrassed about asking but I don't have a lot of options besides waiting for an appointment. Thank you
