Lump in outer labia???

So I was examining myself and it feels like I may have a lump in my right outer labia? I can’t tell if it’s a lump or just my skin being thicker/longer on that side? What could this be? Is it serious?? Has anyone ever felt anything like that before? If I go to like pull up on my outer labia to feel it I can’t feel a lump but when I run my fingers straight across it , it feels like my skin is bigger or something ..

I’m just freaking out , I’m going to call my gynecologist on Monday
