I'm worried, I found a lump on the edge of my cervix. Whatcould it be?

Cervical cyst. Most likely it is a nabothian cyst but make an appointment and see your doctor.
Cyst. Most cysts on the cervix are benign cyst called nabothian cysts. See your doctor to have it examined.
See a gyn. May or may not be anything, and surprised you are feeling your cervix, many women can't feel the cervix unless there is some prolapse, could be a nabothian cyst or irregularity from a previous ppregnancy and obviously u need a pap if u are late.
