I am 30, and have 2 kids. six months after my second kid - this week, my physician found high levels of TSH in my blood (7.62) and suggested that I start with levothyroxin (dose 50, is it microgr?) I am experiencing many of the typical problems such as brainfog, tiredness, muscle tiredness, feeling blue...
I am breastfeeding and the label says that levothyroxin will be passed on to the milk, is it safe?
Are there any other side affects I should be worried about?
I am not comfortable taking hormones is there any other way?

thank You.
