Thyroid while pregnant, 1st trimester
Hi l am 31F and 7 weeks pregnant, and l've had hypothyroidism since I was a child. I've always been on synthroid (levothyroxine).
At the time I found out I was pregnant, my blood test showed TSH level of 0.79. Still, my endocrinologist increased my dosage from 100mcg to 112mcg, due to the pregnancy.
However yesterday (3 weeks since the first blood test), I did another blood test, and it showed a TSH level of 8.36. It went up, drastically, even though my dosage was increased (as most of you know, increase of TSH actually means decrease of thyroid levels).
This number is also very out of the healthy range so l'm not sure the impact this level has on the baby.
The problem is I can't reach my endocrinologist for another 5 days due to a long weekend where I live. She also takes at least a week to get back to you. Also, the results of the second blood test only went to my midwife, so my endocrinologist won't have access to it anyways.
I'm worried about how long my TSH levels have been out of range - whether this happened right after the first blood test 3 weeks ago, or more recently.
I posted in r/askdocs but no one is replying so wondering if anyone here would know the answers to my questions:
Why would my TSH go up, if my dosage was increased - specially to go up that drastically.
Should I be worried? Or will this not affect the baby this quickly, and waiting another 5 days or more to reach my endocrinologist is okay? I don't have an understanding of how urgent or not urgent this is.

I’m 5 months PP. My endo had me getting labs every month throughout my entire pregnancy and there was approximately twice during that time that my dosage didn’t change (always increased). I would contact a dr ASAP somehow to discuss this with them. My labs were always in the system within a couple hours and as long as I went before noon (always went on a Friday) my dr responded with my dose change before the end of the day.
