Thinking about getting a female yearly check-up.

Makinzie
I'm 19 years old, sexually active and use protection. I've talked to my doctor about what age is best to get a check up down there. I was told its 21. Honestly I think it should be when your sexually active. But anyway, I've been thinking about getting one done because my mom told me cervical cancer runs in our family and it's better to be safe than sorry. Any suggestions to help the non-stop anxiety or nervousness as soon as I think about it, or what they'll do or say. Could anyone explain how it feels, what they do, etc... Thank you in advance!😊
