Hi, I too suffer from rapidly changing TSH levels from month to month, sometimes normal sometimes borderline abnormal, but it has also affected all my reproductive situation too. I also suffered from infertility many many years ago, but finally got my daughter who is now 11, thank god. So even if your thyroid is going a bit whacky, they will still be able to stabilise it if you get pregnant, you will be ok. It's also common for pregnancy to bring on thyroid problems, so don't panic if this happens, they can treat it. Hope this helps. Good luck!
I had 3 yrs of problems in gyno dept which, btw, totally went away when I became regulated on Synthroid for a whole 'nother reason. All those years they said all was "normal" but normal for me and normal for in-range seemed to not make a difference until they all see it in black and white now.
Ask for repeated tests if you feel any different. And use the thyroid tracker here as a tool to show your docs .. when they see the #'s with the symptoms they may listen more closely!
