Baby heart beat

Bought a Doppler today and heard my babies heart beat for the first time. I've recorded it and can't help listening to it over and over. There are so many stories on here about miscarriage and nothing being there that I've spent the whole time terrified since in the UK the first time I get any proof it's in there is the 12 scan. At least now I know it's there and I can almost cry I'm so happy.
