I have hypothyroidism and a large fibroid the size of a fist on the side of my uterus

I have hypothyroidism and a large fibroid the size of a fist on the side of my uterus. My thyroid has been difficult to keep in check. But with the help of my integrated care physican who prescribed armour, a nonsynthetic  thyroid, my levels balanced out. We have been trying for 6 months! We found out on Sunday that we are pregnant. I am 5 weeks along. We are very excited.
