i have always had pretty irregular cycles. mine was due to ovarian cysts. i agree with the comments above. please go and see a physician.
You definetyly need to go to the doctor. I am very regular with my periods, but had issues getting pregnant - I went to the doctor and it turned out that one of my tubes is blocked.
hi have you been to a doctor? Have you had any test done? If it has been years since you were trying to conceive, then you should have seen a doctor a long time ago. I'm only saying this because if you don't get preggers within the first year then you need help.
