Late/Missed Menstrual Period

[JEA_1461]

I was diagnosed HypoT and began taking 50 mcg of Synthroid in mid-September.  Up until I began taking synthroid my periods, while not exactly occurring like clockwork nor 'normal' (sometimes long, sometimes short) did at least occur within 26-30 days apart.  My last period started on Sept 24 (more or less on time) and dragged on for 12 days (not completely unusual) and I haven't had one since?  

Is it normal for periods to become more irregular/absent when taking synthroid?  Has anyone else had late/skipped periods *after* starting the medication?  I've been taking the meds for close to 8 weeks now and if anything, my period has become more irregular.  I've also been having serious mood swings (mostly depressive) for the past 3 weeks?  Does any of this sound familiar?  

To the best of my knowledge...late/missed periods are associated with HyperT, or am I wrong?  

Has anyone else had this, or something similar occur?

Thanks,

Janet
