| Your thyroid and thyroid meds can alter your monthly period (as can stress and your age as the first poster said). Once I was on thyroid meds... I skipped 2 months, then had 3 periods within the next two months. I've been trying to find the right medications/dosages for the past year (since diagnosis) and my periods are still irregular. |
