Red bump

So I shaved Tuesday and I used coconut oil and I had protected sex that night.. usually when I shave the hair grows back and it itches really bad so when I went down there to feel it I felt a smooth red bump on my left vagina lip near the entrance.. I have hair down there so I shave in that area.. it doesn’t burn when I pee everything is just itchy what could that be? I’m setting an OBGYN appointment for it. Not sure if pictures are allowed so not posting it
