10 weeks bump....doppler induced worries

Hey everyone :) so this is the first pic of my bump I've taken. I'm a bigger girl, so I'm afraid I won't get rid of my "b" belly, but there's hope :)

I had my 10 week appointment last night. I've already has 2 ultrasounds. I've seen and heard the heartbeat on both. My doctor tried the doppler last night. He said it's very early to hear it easily on one and I probably won't hear it, but he tried. We couldn't hear anything. I know it's normal, especially because I have more "padding", but still induced some worries in me. He's not concerned at all. He said I probably won't hear until about 14 weeks. I kind of wish he would of never tried. I'm really trying not to be a worry wart.
