Fainting and falling flat on my bump

Niamh
Hi guys. I have been having very Bad fainting and blacking out episodes over the past few years, but with pregnancy they have intensified. Last Thursday I fainted, falling firstly on my bump then my face, which required stitches. I was monitored and all seems fine with baby but I can't shake this horrible worry of the damage I might have done. Any one in a similar place. I'm 29weeks. Thanks
