Has anyone had heart palpitations while they were pregnant. I’m getting to the end of my pregnancy and I am getting worried about delivering because of them. I saw a cardiologist about them and they weren’t concerned at all they said it was because my body is making more blood but I already have a 2 year old and my irrational pregnancy brain is just thinking what if something happens to me during birth and I leave both of my babies with out a mom. Just getting worried that they will affect my birth.
