Little bumps on the corner of my lips?

Brianna • I love going to concerts and raves! Life is all about new experiences and enjoying what God has offered us!☺️💕
I just found these today. They're supper tiny and they don't hurt, but I just have a lot on the corner of my mouth. My right side more than my left actually. And they're actually inside my lip as well (closer to my lip line inside)
I have done oral on someone, but he never mentioned an STD (I know, my fault) but can it be an STD? I don't have any pain and i haven't noticed anything different with my body, although I am going to start my period soon. 
I have had little tiny bumps on the very outside corner of my mouth, since I can remember but I don't know if it's the same thing.
