I was diagnosed with hypothyroidism 7 months ago and my Levothyroxine dose has increased incrementally over that time to 150. My periods have also become irregular. I'm 48, so approaching menopause may be the cause - it's just that this change coincides with the time I've been taking the medication. I just wondered if anyone else found their monthly cycles altered when they started taking Levothyroxine?
