Just been diagnosed underactive thyroid

Hi I've just been diagnosed with an underactive thyroid and started levothyroxine. We have been told my thyroid is the reason I'm not getting pregnant so fingers crossed we get our levels down to the ideal range the fertility clinic want it at which is 2.5 or lower and we get or bfp soon.

Still very new to this and trying to learn more about the condition in general as alot of the symptoms actually are disguised by my fibromyalgia so hoping once the meds are in my system I'll feel abit better then I do now .

Any advice you ladies have on dealing with an underactive thyroid would be greatly appreciated.
