Swollen next to clitoris! (TMI)

So two days ago I noticed a really bad pain next to my clitoris and saw it was really swollen. It’s not the clitoris, but right next to it. You can barely even see my clit! This happened the day after sex. And I also just got my period two days ago. Don’t know what caused it or if it’s anything serious if I should see a doctor. It hurts so much, I can barely walk without being in so much pain. Does anyone know what it is or how to fix this? Please help! (TMI)
