Vagina swollen

So I lost my virginity a little over a week ago and we had sex again about 4 days ago but it was a lot harder and I don’t think I was as wet but now I feel like the outside of my vagina is swollen and when you first inter it kinda hurts not sure how to describe the pain but ya. I also had a BV about 2 weeks ago not sure if that matters. But can you help me
