When I had my second beta drawn on Thursday my TSH (thyroid stimulating hormone) was elevated. Not off the charts elevated, in fact it was still within therapeutic range, so not horrible, but concerning just the same. Since the prescribing physician is not my RE, they are requesting that my PCP (the prescribing physician) monitor and manage my thyroid care. Thankfully I was able to make an appointment for Tuesday to check in with my doctor and see where I need to go from here. I'll be five weeks tomorrow and hope the changes in medication will take effect quickly. When I started thyroid medication last year within 4 weeks my level had nearly cut in half and within 8 weeks it was less than 1/4 of what it was when I started, so I'm feeling pretty confident that we caught the rise early and it will quickly be remedied.
When I consulted Dr. Google on the matter I read all kinds of scary things, but I also read that high levels of HCG (hello 889 @ 11dp5dt) and increases in estrogen (2036 @ 9dp5dt) can elevate TSH. My RE reduced my estrace dose down to 2mg /day from 4mg/day starting last Wednesday, so that too could help improve the levels. We'll see.
The moral of this story? Even if you don't have thyroid issues pre-pregnancy it is a good idea to have your levels checked early in pregnancy. It isn't something my clinic tests right away, so I had to ask to have it done and I'm SO glad I did!
I'll be sure and update tomorrow after the appointment!
