TSH level 3.60 at 4.5 weeks pregnant

Hi all,

I am currently on levothyroxine to lower my TSH levels. I had a blood test 2 days ago confirming my pregnancy, but that they are concerned because my TSH levels are at 3.60. They wait it’s technically “normal” but “too high for pregnancy.” Of course, I googled it over and over again, and now I’m concerned that I could have a miscarriage. Has anyone had this TSH level and had a healthy pregnancy?
