Approaching the second appointment

I officially meet the doctor tomorrow. It's my second appointment and I'm a little nervous. I'm hoping we get to hear the heartbeat. I just want to confirm it's still there, beating away. I'm ready to move into the second trimester and I'm ready to purchase some baby supplies! I found the cutest car seat online the other night and every impulse in my body is urging me to just order it! Mark on the other hand is being the voice of reason and reminding me I don't need to order our car seat at 12 weeks. Maybe he'll at least let me buy another onsie or something this weekend! :)
