Having hypothryriodism myself, (after pregnancy), I can say that you shouldn't be messing around with trying lots of herb remedys now. You have to get this thing under control first, and then maybe try other things. Herbs are tricky things, and work differently on different people, are not predictable in how they work over time, etc. Too much unknown. Levels over 5 are considered hypothyroid, and need medication. So, a level 115 is dangerous. You don't have precious time to play with herbs right this moment.
A good book to read is, "Living Well with Hyprothyroidism," by Mary J. Shomon. She is a leading expert on the subject, and will answer a lot of questions you might have. She quotes K.P. Khalsa, a known world's premier herbalist, on page 125...
"You probably can't really self-treat an autoimmune disease in general, as you have to take the whole body point of view to get better results."
Generally, the idea is that a thyroid problem is NOT a quick fix, (it sometimes take up to 4 months to see what your level of meds are actually doing for your body), and it sounds like you really need to be there now for your little one.
I hope you start feeling better soon. I know it's a hard road and it's a shock to your mind right now, but you will get through this.
Hugs and prayers for you.
