Ttc #2 and under active thyroid

[AppleMum29]

Hi all, just joined up as me and the OH are ttc number 2! I had #1 in 2010 after one month of trying after the pill no problems but a c-section birth due to complications. Found out two years ago I had under active thyroid so commenced on levothyroxine 100mg and 50mg every day!

We have started ttc and I have been taking pregnacare conception also it's early days. I am just concerned about the thyroid and haven't been to the doctor as yet to speak about thyroid and ttc. Anyone else here that has the same problems with under active thyroid and ttc?

Applemum29 and mercibucket, that is exactly what my GP said- that my levels were fine, but the Endocrinologist said that what is fine for general health is not the same in pregnancy and since the baby starts drawing on the reserves immediately, he wants patients as low as possible (but no lower than 1 as this can then make you hypothyroid and put you at the risk of miscarriage) so that there is no chance of the baby receiving inadequate amounts. My hubby and I were upset that our GP didn't advise us of this as it could have put the foetus at risk if we had conceived but I guess they can't be experts in everything.

I'm going to type out one more important bit which I just about understand: 'it is common to see suppressed TSH during the first trimester due to thyroid stimulation by HCG (pregnancy hormone- I had to look it up). This should be accounted for when assessing throid hormone replacement in the first trimester. In the second and third trimester, there is still some assay interference which results in spurious decline in free T4 levels. It is important that these are accounted for when determining the dose of Levothyroxine: pregnancy- corrected reference ranges should be used.' Worst way, you can print that out and show your doctors!

He didn't mention taking tests at any particular time- I just have mine whenever. I also take my med at night even though they advise morning so the stomach is totally empty- I've done it from the start, so think that all my blood tests have been worked out on that basis so it's probably best for me not to switch!
