Hello, I Am A 15 Year Old Girl. I Lost

Hello, I am a 15 year old girl. I lost my virginiry about a week ago. I've had some pain and swelling on only the left side of my outer labia? It doesn't hurt unless pressure is applied. It almost feels like a large vein underneath the skin. When i squeeze it it feels like it dissapears only to show back up again. It's only been there for a couple days but still it concerns me. Is this something I should be concerned about? Thank you so much.
