Not really Sally although there were the odd occasions where I would get dizzy from standing up too quick. Towards the end of my pg I had flashing lights and severe headache that wouldn't go away and my kidneys weren't functioning properly hence my induction. After my DD was born that I had heart racing I don't know whether it was from the meds I was on or not. I do know though that when you are pg your blood volume increases by 20% so your heart has to compensate and work harder to pump it around.

I suppose worrying about it being high isn't going to help either lol I hope I haven't scared you xoxox
