Currently at ER

I saw the baby she told me she wasn’t supposed to let me look and she can’t tell me anything but I heard a heart beat. I was diagnosed with Hyperthyroidism last year and AFib three years ago. Dr. Only said the cause of my nausea and current palpitations is hyperthyroidism I haven’t been on any meds since finding out I was pregnant. Any one else dealing with these issue I have lost 10 lbs in the weeks leading up to finding out about pregnancy. I’ve been here 4 hours and I’m getting nervous anyone else dealing with a heart condition
