I have been taking seasonique for at least 2 years and have always had regular periods. i've started 2 weeks early and am having terrible cramps.

Watchful waiting: For 36 YO women using extended-cycle OCP's and starting menses 2 weeks early, I suggest watchful waiting at this point. Sometimes anything different in our routines (stress), weight gain or loss, an antibiotic, even an over-the-counter supplement can cause metabolic fluctuations and result in early shedding of the uterine lining (menses). Continue on your usual dose and keep track of menses.
