It's highly unlikely you'd have hurt the baby in your fall.

But obviously you *are* worried. At this stage it's quite possible that your baby's heartbeat could be picked up on a doppler, so if you were to go to your midwife/doctor, they would be able to have a listen for you. (It isn't guaranteed to pick it up, however, and you may want to request a quick scan to be sure.)

While you might have been feeling flutters before your twelve week scan, it's highly unlikely it was the baby moving... but even if it was, the position can make a huge difference and at fourteen weeks you might feel one or two movements but then absolutely nothing.

Bubs will be fine, but my advice is to buy a doppler from ebay. Very reassuring to hear that heartbeat whnever you want!
You know, I really really don't recommend this. Firstly, there have been no longitudinal studies done on frequent exposure to the frequencies emitted by the doppler and for caution's sake I'd keep this kind of thing to a minimum. But secondly, I think it's really healthy for women to settle into their bodies and give them a bit more credit. I know there are tests and checks for everything, but I seriously don't think they make for a happier pregnancy. And at fourteen weeks, even up to twenty weeks, it's likely that an inexperienced user is not going to be able to pick up the heart beat easily, leading to fear and anxiety. And stress *is* a proven risk factor for pregnancy outcomes.

Best of luck.
