Early reassurance ?

Thought I would just remind u about the my baby's beat app 
I wanted to get a Doppler but it costs quite a few bucks so I thought £3.99 (I'm in UK) wasn't too bad to see if it works 
I haven't had a scan nor has my midwife checked the heartbeat 
So I just wanted to know that the wee heart is going 
N it did I would add my recorded beat but dont know how lol 
It is very clear n easy to use n def settled my anxiety 
Especially that I can just whip my phone out pretty much anywhere quiet n listen to that prescious heart beat. 
I am 10 w 4d gone 
That's what I think but I could be slightly lying since I haven't had a scan yet. It's worth a try tho 😌
