Hi, I am having very regular cycles. In March 2019 I had on and off spotting for 20 days and I have gained weight.
TSH was 4.3. weight gain continued so consulted endocrinologist and started using thyronorm 25 mcg from June 1st 2019. My last menstrual period was on 18th May. I have missed my period this month but there are no pregnancy symptoms. I have checked for ovulation for two weeks for this month, all turned negative. What might be the reason I have missed my period?
