I never had regular cycles until I talked with my gyn back in 06. I'd diligently tracked my cycles for the previous year, noting the start of each cycle and the last day of bleeding on a calendar. I didn't pay much attention to the length of each one so when she counted out the days, even I was surprised to learn my cycles were 40 to 60 some days long! She wrote a referral to fertility on the spot and also had my thyroid levels tested. I was borderline hypothyroid, not showing any physical symptoms, but 6 weeks after starting hormone replacement meds, I got pregnant. Miscarried almost immediately though. Four months after the miscarriage, I was pregnant with my first son.
Definitely talk to your doctor! Irregular periods are nothing to shrug off; they're a sign that something's not right and usually it can be corrected pretty easily.
