Heart problems while pregnant

I’m at a loss.

I’m 13 weeks with twins, and for the past week and a half I’ve had painful palpitations day in and day out. I’ve been to the ER twice and both drs said it could be either my thyroid or “the difficulty of a twin pregnancy”. I can’t get into an endocrinologist until March 2022. I’m hoping my OB can do something about it.

Has anyone experienced this? I’m to the point that I’m extremely self aware of every palpitation and when they happen it hurts and takes my breath. I’m so afraid I’m going to die. Hyperthyroidism? Or twin pregnancy? I have 5 kids I don’t want to leave in the world without me.

Oh man this sounds like an emergency…please reach out and tell a doctor again. Something is not right
