The pill

Well basically I thought I'd come here to turn to a Group of women asking for advice! I'm going to the doctors tommorow to go on birth control because me and my boyfriend want to be safe and the best thing to do is go on the pill.
​I'm really nervous about going god knows why! I'm 16 years old nearly 17, I know I sound so stupid but yeah ahaha Can people tell me what questions they'll ask etc just to clear my mind as I can't sleep thankyou for any advice hahahaha x
