I found my babies heart beat!!!

I'm so excited! I got a Doppler last week & tried it out right away... and found babies heart beat a couple times but only for a second! I just tried again & baby actually stayed for a full minute so I could hear it! It was so amazing! Then baby kept moving & I had to keep chasing. I don't think he/she likes it. But anyways, I have only had one US done and haven't had any dopplers in the office yet because I'm only 10 weeks, so this was my first time hearing baby's heart beat!!! HR 173-180 😀
