I understand that less frequent and lighter periods can be caused by HYPERthyroidism but what about HYPO?
I've not had a period since last August. I'm 43. My hormone levels were checked, found to be high, checked again and found to be normal (FSH)....... But still no period!
I'm on 50mg levothyroxine. If anyone knows or has experience relating to this I'd be really interested! Thank you xxx
