After 5 weeks of pregnancy, my heart starting feeling a little odd. Now I am 7 weeks, and the other day I felt a strange sensation in my heart and then I was dizzy and my head felt numb and tingly. I am afraid of going to the ER or urgent care because my son almost died from contracting a virus en utero, and I am trying to avoid that sort of atmosphere. I have an appointment with a doctor in a couple days, so I can put my fears to rest soon. My question is, has anyone had heart problems or weird heart issues during pregnancy?
