GYN QUESTION

So I first went to the GYN when I was 13 because I had really bad acne so I was put on BC in hopes of it fixing it, the pill was too strong for my body so I went off and went back on when I was 15, I'm now 17 and I've been getting like a heavier period and worse cramps than normal, I normally have no symptoms so I have an appt this Friday and they said since I haven't gone since I was 13 I need to see the doctor. Since I have lost my virginity, but my boyfriend and I broke up so I'm currently not sexually active. Do you think it matters if I tell her? And are they going to have to do the whole exam thing? I've never gotten one and I'm actually kinda anxious over it
