Hi i'm 26yrs old and have been trying to concieve my first pregnancy for 10 months. 4 months ago i had bloods done which showed a TSH of 7.6 ( 0.1-5) t4 was normal. I was commenced on 25mcg thyroxine and 8 weeks later my TSH was 3.4. My gp was happy with this and didnt want to increase my thyroxine. My concern is im still not pregnant and was wondering if this could effect it. Thanks.
