I first went for an appointment when I was 13 I was having terrible cramping and extremely heavy periods.
I was nervous, but my mom explained everything to me before the appointment.
The Doctor and Nurse were very nice and told me everything to expect. It was also kind of nice to not have my mom in the room for the whole appt, so I could ask some questions.. Nothing bad, just wanted more information about about tampons and some other stuff, I was embarrassed to ask my mom about and I did not want her in there for the pelvic exam..
I took our daughter at about the same age, she also had terrible cramping and heavy periods, she also had some other issues we were not aware of so I was glad I took her.
I asked her, "do you want me to go in with you, or would you like to do this on your own." . She said, "on my own please." So I thinking asking your daughter is always a good idea.
I really tried to just make it matter of fact. She was already kind of put out that boys would never have to go through menstruation .. so she was really not pleased about this exam.. Hee, hee.
