Hello! I've had five miscarriages: three that I believe were caused by my hypoT if not all of them (undiagnosed and untreated at the time). My lab values are in the "normal" range but for me that's not good enough. My FT4 levels are still low and I've read that for optimal fertility health they should be in the upper third of the range (for me that's above 1.5 since my lab range is .8-1.8; mine are currently 0.9).
I'm pregnant again (unintentional but happy about it anyway
) but a little nervous because my levels aren't very good yet. I would recommend a reproductive endo if there is one nearby. I'd like to take my own advice but there's a long waiting list which makes going there moot since if I could make it to four months and still be pregnant I probably wouldn't need to go
Anyway, I strongly recommend what the others have said: ignore the TSH and get your FT4 into the upper third of the range.
If you are truly hyper your periods would most likely be nonexistant and you wouldn't even be considering TTC since you wouldn't be cycling. I personally bled for three weeks out of every cycle when my FT4 levels were at their lowest (had an ovarian cyst burst which ended up okay but then hemorraged during my last period...not fun!!). So the thyroid has potential to wreak havoc on the rest of your hormones as well.
I hope that it won't be a long wait for you but I really believe that it's worth the wait to start a pregnancy as healthy as possible. I was kind of sprung into this one and it's a little nerve-wracking. Having my hormones leveled out would have added some peace of mind.
Love and Prayers, Kelly
