Hi I'm 19 and a virgin. I've had irregular periods since I was 14 I was always told they'd straighten themselves out after a few years, but they didn't. I made my 1st appointment to go to the gyn, and I'm nervous on why my periods are so irregular. Is this a common problem with girls my age that can be taken care of fairly easy with medication or something. Or is this something really serious? Which one is most likely? Thanks for the replies I'm really nervous?
