I know it sounds like an odd question, but lately I can sometimes hear my heart beating in my head/ears...like a pounding...even when I lay down to go to sleep it can be there. It does seem to happen when I get up from sitting and start moving around, or sudden bursts of activity I guess, but is not specifically linked with exercise. I am wondering if it's to do with the increased blood flow in pregnancy?

I had this as a symptom when my Graves Disease was right out of control, only it was much worse. I don't think that is the cause now however, as my thryoid levels are currently normal.

Anyway, just curious if others have experienced this as a pregnancy symptom?
Thanks
