I too have/had irregular cycles (amenorrhea)in the past and after having 2 children it got to be a once a year cycle which is bad because it can lead to osteoporosis. It also lead me to secondary infertility and developing Polycystic ovary syndrome. I had to use fertility drugs to conceive my 3rd child and by pure miracle conceived a 4th. I reccommend that you see your gynecologist and he will probably offer birth control to regulate you (patch or pills). I have also received shots in the past. Hope this info helps and guides you to the gyno.
