Hypothyroidism

Hey all! I’m pregnant with my first and I’m currently 9 weeks and 1 day. Feeing pretty good, just exhausted and need to be munching or else my stomach feels like it starts to eat itself. A month before getting pregnant I got diagnosed with hypothyroidism. The doctor started me out on a low 25 mg dose of levothyroxin and I’ve been getting monthly blood tests and they have bumped me up to 50 mg and they just called me to say that I’m at a healthy t3 and t4 level for a “normal” human but not for a pregnant one... so they bumped me up to 75 mg today. I need to go in for a blood test again in 4 weeks.

They tell me not to worry, that adjusting dosage during pregnancy is normal and just needs to be monitored. I just get nervous because we just now found out a dose that would’ve worked for me before I was pregnant... and I’m now in month 3 of pregnancy... just a little anxious but trying to stay calm. Anyone else go through these dosage changes?
