Post sex vagina weirdness?

Alexi
Today I had some pretty rough sex. And afterwards I had this weird part of my inner labia (i think it was that area around where my clit is) was puffy and sticking out. At first I thought something squished out from me. To me honest I hurt a little and freak my boyfriend and me out I took so ibuprofen and the swelling when down after like 4 hours later. If anybody has had this happen to them or knows why let me know.
