Any mommas with an under active thyroid?

Hi! Looking for some advice from other mommas who have an under active thyroid!

I’m about 4 weeks along in my first pregnancy - I’ve gotten my 8 week appointment scheduled for April 17 with a new OB. I have an under active thyroid and have been on levothyroxine for about 3 years now. Because the OB hasn’t treated me before, they said I’d need to go to my regular physician to check my levels to make sure my meds don’t need to be adjusted. My physician isn’t able to see me until March 28 - is it ok to wait 2 weeks, or should I push to be seen sooner?
