I am certain my TSH should be between 1-2 , however im not exactly sure as to why....
Is it that it should be in that range so that when you fall pregnant you have your thryoid level where it should be so the baby is getting all of its needs? As i know in pregnancy the highest your TSH should be is 2.99........so having it consistantly between 1-2 before conception would indicate the thryoid is somewhat under control and will be easy to maintain during pregnancy........although i know most ppl have to increase there oroxine during pregnancy to maintain this level.
OR
does having your TSH between 1-2 actually make you more fertile and increase your chances of pregnancy cos this is where a normal person's TSH would be?
