TSH levels

Katie
After having thyroid issues for 14 years since I was 12, I just found out that my current Thyroid Stimulating Hormone (TSH) level is 4, when the ideal level for conception and first trimester is no more than 2.5. We just started TTC and I will be taking a test on Friday, but I am worried now that my body is not prepared for a baby if I am indeed pregnant. Chemical pregnancy is a very real possibility as I have experienced what I feel like are early pregnancy symptoms. Just worried and trying not to stress or Google about all of the negative possibilities anymore.
