Nervous about gyno appointment

Hello, I’m 20F and will be seeing a gynecologist soon due to some abdominal pain (they already determined it wasn’t appendicitis or anything, next thought is something ovary related) as well as general really painful periods. I’m nervous because I really don’t like being touched near my breasts or vagina (as in absolutely cannot tolerate, just the thought of anyone touching me there makes me cry uncontrollably, no joke), and I know you can say no to anything, but I feel like this would defeat the purpose of a gyno since most of their exams seem very invasive. I’ve never been to a gyno, and I’m very scared for it, I have pretty severe trust and touch sensory issues. Just looking for advice, thank you.
