Hello, Irregular cycles essentially indicate a disturbance in the normal hormonal pattern of the body (HPO-axis) and these maybe caused by a variety of factors, some of which are polycystic ovaries, abnormal thyroid hormone and insulin levels, abnormal weight, stress,use of certain medications and so on. Some situations are familial, but most of them can be treated with modern medicine, so you need not worry at all. See a good infertility specialist who will work up you and your partner for cause and further management. Good luck.
