Irregular Cycles

So, I've noticed I have irregular cycles. They are always within 25-35 days, but each month varies, sometimes quite a bit. Is there a natural remedy I can try or do I need to be medicated? I used bc for several years, but I've been off that for about a year now.

I never considered it to be so irregular until I started TTC and was temping, etc. Sometimes I feel like educating myself about this has only made me stress more. *sigh*
