I saw my doctor a couple of weeks ago because my period is all over the place.. some months I get it once and others twice. She checked my hormones and did swabs which all came back normal. The length of my cycle since september is 14, 16, 16, 15, 29, 31, 14, 13, 16, 17. Does anyone else have a cycle like this? Ive read birth control can solve this problem but Im not sure where to go from here. I have written this down to show my doctor tomorrow but wondered what other people had done about it.
