I’m not sure how to navigate this

When I (24F) was younger, my mother would periodically tell me to lie down on the bed, where she'd proceed to 'examine' my vagina to check if I was having sex or still a virgin. I had my first Pap smear at 14, and I felt violated that she was there with me; I believe the doctor intentionally tried to make me feel uncomfortable. The doctor’s attempt at reassurance was, 'You'll understand when you're a mother one day. Over the years, I've had other traumatic experiences, leaving me terrified of visiting the gynecologist . My last appointment was three years ago, and it was another distressing experience. How can I overcome my fear and power through this?
