I'm new here and just wanted to give a bit of background first.
DH and I have been TTC since July. We had a early miscarriage/chemical pregnancy and 4w6d in October.
I'm aware that we haven't been trying for long, and that there is no need to be concerned. However, I'm worried that my thyroid could be impacting.
I was told that I was subclincally hypothyroid a few years back. Never treated, as my levels are always 'normal'. Despite this, I do have symptoms of an underactive thyroid (hypothyroidism), such as fatigue and sensitivity to cold
I've had my levels back last week. My TSH is 4.6 (range 0.5 - 6) and my t4 is 11.6. (don't know the range, sorry)
I've seen a number of times that TSH should ideally be between 1 and 2 when TTC.
I'm worried that this could affect us TTC. Even more so, I'm worried that this could be the reason for our early loss in October. I know it's probably not, and that early loss is very common, but I just wonder if the doctor should have mentioned this to me when I told her I was pregnant.
I saw my doctor today (a different doctor to the one I saw in October) and he told me that my levels are well within range and that there is nothing to be done basically. Even when I explained all the above he just repeated that they were in range.
I feel like I have a million questions. I don't quite understand how the ranges work, are they based on an average or is it more than that? I also don't understand why I keep reading that levels should be between 1 and 2 for ttc if my doctor disagrees - he said he'd never heard of that before!
If anyone could give me any advice around this I would be so grateful, thank you.
