Just wondered if anyone has been in the same posistion as me and want to hear your stories.
I was diagnosed with Graves' disease at 17 and had my whole thyroid removed at 20. I am now 25 and 17 weeks pregnant with my first child. My doctors have been keeping an eye on my blood test results and have been told they are normal up to date. However yesterday I saw the endocrine specialist who said my bloods are not normal and they have been low up untill now!
May tsh 17 ft4 20.6
June tsh 4 ft4 19.7
July tsh 2.5 ft4 17
My doctors thought my tsh needed to be below 5 but endo says below 2!
My endo has upped my tablets but I am now worried that because I was low for so long in early pregnancy that there will be problems with my baby.
Looking for others in my position of mums who have had successful pregnancies so I can stop worrying!!

Star2013, the TSH of women trying to conceive and newly pregnant women should be in the low-normal range 0.4-2.0 with FT4 in the upper quadrant of range.
The foetus is dependant on maternal hormone for the first trimester so your TSH may have been high in May due to foetal demand.
If your 13 week development check was good I don't think you need to worry. The baby will have developed its own thyroid gland by then.
Thank you for your reply, that makes me feel better. All my checks at my 12 week scan where normal and also my FT4 has been normal my whole pregnancy so far which I've heard is actually more important then the TSH? Obstetrician isn't worried either and wasn't even sure why she had to see me because she doesn't see any risk. Just my endocrine doctor who panicked me and said I might have problems because of that May test.
Star, high TSH significantly increases the risk of miscarriage but baby has stuck with you so it was probably his/her demands on your hormone which shot your TSH up.
The dose increase your endo gave you will help to prevent post-partum thyroiditis which is also an increased risk when TSH is high during pregnancy.
