Discussions that mention synthroid

In May my doctor put me on 25 mg. of Synthroid. I was having extremely heavy and long periods at that time. In June, my period was much lighter. In July, I was put on Armour - 30 mg. I haven't had a period since June 11. Has anyone else stopped having periods due to thyroid meds? I am 46 years old - this could be menopause - but I think it's the meds? Any input is appreciated.
I supposedly (only excuse they could come up with) went hyper on Synthroid and Cytomel last year and didn't have a period for quite a few months. Now I am on Armour and haven't had a problem yet.
