Evening all, people might remember me from questions I had in the autumn- I had been feeling awful for ages and had also been trying for baby for almost 2 yrs... I was eventually tested for TSH, found it was high and after a battle with all of the GPs at my surgery, a locum agreed I needed levothyroxine for hashimotos to have a chance of trying to conceive. ... My TSH came down quickly and I felt better within 2 weeks- it was a revelation! Now the hopefully good news- I tested positive for pregnancy last week.. had HCG for pregnancy confirmation and also TSH test done today. hCG has confirmed pregnancy! TSH has gone up slightly- from 2.6 to 2.9. T4 has not changed at all- exactly the same at 16.4 pmol. My GP (same one who doesn't agree with treating unless is reaches TSH 10) has said that is fine, I don't need to amend levo prescription. Is this correct? It may be but I have lost confidence in him now. Thank you once again for any advice.
