Just a thread to see if anyone is/has experienced similar. I am currently 34 weeks pregnant & for the last couple of days my heart rate has been super high- been in to my local day assessment that have done tests etc and can't get to the bottom of the cause for it. I am booked in for heart scan etc in the week... has this happened with anyone else & did it affect your pregnancy? It sounds silly but it's making me really nervous about going into Labour and having a high heart rate!
