Breast lump

I am 19 years old and the past 2-3 months my left boob has a small pea size lump that has now been aching for a month now. It is intense pain when I touch it but it’s so small. I don’t have any form of insurance and it takes week to get into my doctor. I don’t know what to do and I’m scared. The thought of possibly having breast cancer is nerve racking. Someone please help me and give me feedback if this has ever happened to you, what happened, and what you did.
