First off I am 22 and have never had a regular cycle. It has been 3 months since my last period (No I know I am not pregnant!). I have skipped a long while before but geesh. Does age ever make you regular? In 2007 I hadn't had a period in about 2 months and went to GYN. She gave me birth control and also suspected thyroid issues because of me being on Lithium (didn't help me anyway!) Turns out I had a underactive thyroid. Since then I have been taking the meds to correct that and have had no other problems-all is normal now. In February this year...same thing and got birth control. Had to stop taking it because of work and all.

What do I do? Is it bad for the body not to have a regular period? Should I do anything about it or just flow with it?
