Any hypothyroid mom's out there who can give me advice?

Hello! 🙋🏼
I'm 16 weeks pregnant with my first kid. I've had hypothyroidism since I was 18 and it's been a trip. I have no idea what to expect for the rest of my pregnancy or for when my baby gets here. 
How do you manage the debilitating fatigue as a new mom? 
I'm so happy to be pregnant and to get the chance to be a mom. My husband and I tried for two years and we finally got this miracle baby. A part of me is so anxious about what it will be like to be a new mom with this illness. It might just be a feeling of inadequacy bubbling up, but there are some days pre- and post-pregnancy where it's all I have to get up and take a shower.

If it helps, right now I'm taking 90mg of Armour Thyroid. I was doing very well before the pregnancy but of course my endo is watching like a hawk to make sure my TSH is under control. 
Any advice is appreciated!
