Hi. I m 28 yrs old n din have my periods this month (last period was in the first week of may 2014), did hpt twice one on 16th n other on 20th June which was negative. I have hyperthyroid n on medication of 50 mcg thyronorm. I had my tsh tested in last week of may 2014 which was normal n doctor advised me to continue wit same. I m gaining weight since my last period and l always had proper periods before. i m worried alot wat cud be the reason for this weight gain n missed period though i don have stressed life? I had a constant weight for years even with thyroid disorder, now though it is normal Wy am i facing these issues??
