Inside vagina

Whilst exploring recently, just a bit into the vagina I can feel little tiny round lumps. I don’t know if this is normal? I can feel maybe 2 one side & 1 the other. They are really small bumps along the grooves naturally in the vagina. Can anybody help me with this? My partner has never commented on this but I am insure as to whether they have just appeared or may have always been there. As I say they are kinda to the side a bit. Thank you
