Scared with graves disease

We’re planning to have a second child in the family. My first child is healthy and no complications throughout the pregnancy. My thyroid levels were easily managed during my first pregnancy, it wasn’t severe that time. I’m now 36 years old and I only have hyperthyroidism/ graves disease. I have no other disease, bad heart condition or diabetes. I’m also seeing an endo for thyroid. A few months back, I could conceive again but sadly the pregnancy didn’t go thru. I had miscarriage which really broke my heart. I was very hopeful. Now i’m devastated and worried. Our whole family is really longing to have another child. But my worry is killing me. I know early miscarriages are common. But I’m extremely scared to have another miscarriage or have health complications with the pregnancy/baby. If there is any mother out here who gives birth with hyperthyroidism, can you please share me your stories.. i’m in need of encouragement..
