Big (((HUGS))) Kara! Please let us know what you find out. I'll be thinking about you and praying for you.
Leslie, I was diagnosed with Graves Disease after my second was born. I really struggled with the symptoms for a long time before we realized it wasn't just postpartum hormonal stuff. I'd be happy to talk with you about it. Just make sure you have a good endocrinologist and that they are keep track of your TSH, T3, and T4 levels.
And, good luck to all the rest of you preggos.
