a pea sized hardish lump in my vagina opening

I was showering about 3 months ago and right at my opening in my vagina I felt a pea sides little lump, it doesn't hurt or itch I don't have any symtoms it's just there and it worried me here and there no it hasn't grown and yes if have sex many times with it and nothing has happened it's just weird to me and I don't have insurance or anything to help me with the cost of appointments and examinations

It's like right at the top of my opening inside no it's not my cervix it's not deep inside at all I can feel it without pushing my finger inside it's just a little concerning to me but I'm also not to too worried I just need opinions pls 🙏🙏🙏
