Irregular Cycles. Irregular cycles usually means irregular ovulation (release of the egg from the ovary). Most of thes women have trouble getting pregnant because they do not know when to have sex to get pregnant. We have medications that are inexpensive (clomid (clomiphene) $60/mo) to expensive ($4000/mo). See a fertility doc and then get the right medication because it works very well.
Evaluation important. Irregular periods usually indicates ovulatory dysfunction. Since there are many reasons what may bring on ovulatory dysfunction (pcos, hypothalamic amenorrhea, hyperprolacitnemia, perimenopause or poor ovarian reserve, hyperandrogenism, etc.) each with its unique treatment options to conceive, an evaluation is the most important first step.
