TSH levels during pregnancy

Am

Hello ladies, I started taking levothyroxine in December before starting <a href="https://glowing.com/glow-fertility-program">fertility treatment</a>. Unfortunately I miscarried in March. I am now pregnant again and my TSH was just checked at 3.0. I am very nervous. My levothyroxine has been increased right away and will be rechecked in 4 weeks.

Has anyone had thyroid issues and medication adjustments? I’m just looking for some reassurance 😌
