Thyroid craziness-kinda long

Colleen
I'm posting because I hope someone can shed some light on this craziness. My doctor called me in for a 645am apt Friday to tell me that my TSH was normal, total t4 was normal, but total t3 was very low. I've been having almost all the symptoms of hypothyroid so she decided to double my synthroid meds. Ive also been spotting every day, with the exception of maybe two or three days this month. Been TTC #1 for 14 months now 😕 and nothing, not even a mc or cp. Does anyone have any similar stories and/or advise? Thanks for reading.
