Where did this fear come from?

I know. I'm shocked myself. Another blog post so soon after the last one? Well, I'm feeling anxious, so I thought writing about it may help a bit. So here goes...
My Dr. appt is Thursday morning. I am so nervous there isn't going to be a heartbeat this time. I know it's very unlikely, but I can't shake this worry. And even though *I think* I've felt movement I keep saying that it's probably just gas and then that worries me, even though it's still early to feel any movement, even with this being baby #2. But although I know that, the fear keeps taking over. and over. and over. I really think I need some serious prayer time - a good conversation with God to let him know what's going on and that I really need some help here! And for Him to tell my I'm being silly and that He has this baby and to trust.
So, with that said, I am really hoping I have some great news to post on Thursday afternoon. Oh, and I'm going to try to get an ultrasound because of the bleeding on Sunday. And who knows, I may casually ask boy or girl and get an answer...
