I had a miscarriage earlier this year, and I'm now 15 weeks pregnant. Due March 30th, which is oddly the day I lost my last pregnancy. My last appointment was 4 weeks ago, and I heard the beautiful little heart beat, but I'm having a really hard time waiting until the next appointment, which is next Friday. I keep thinking something is wrong. With this being my forth pregnancy, I'd figure my belly would poke out more, and it's not. I don't know if I'm freaking out because of the way my last pregnancy ended... or it's just all in my mind. Anyone else feel the same way?
