my tsh was 38.95 two months back and then i was advised to take thyron 50 mg everyday for 6 weeks and repeat the test once again. last month, my tsh level was 5.82 and my dr advised me to continue the same dosage and repeat the tests in 6 weeks. i have been having excessively heavy periods over the last few months and especially heavy the month i started the thyron medication. my dr said that it should stabilise this month. this month the flow was normal to heavy, but i have gotten my periods again within 15 days. is this because of the medication? is it ok?
