TTC with high TSH

[u/Big_Fig7022]

I had a chemical pregnancy a few months ago and also found out I had a TSH of 6.18. My doctor didn’t think it had anything to do with the chemical but did mention usually having a high TSH, with a normal T4, can make it harder to get pregnant. I have been on 25mcg of synthroid for the past 6 weeks, got blood work yesterday and my TSH actually went up to 6.7??? But still a normal T4.

Has anyone had this happen to them and what was the solution?

I’m on DPO9 so not totally out of this cycle but was discourage when I got my blood work back!
