Nerves

I thought after the first ultrasound, seeing that wonderful heartbeat, that I would feel reassured. That I would be relaxed and able to enjoy every minute. But I'm still nervous. I feel really really good this pregnancy. I think that's part of it. Tomorrow I have another appointment and I can't stop myself from worrying that we won't be able to find a heartbeat and I'll have to beg for an ultrasound and what if something is wrong? I know that's not likely now that I've both seen and heard the heart beat. But it's been a month since last time and I can't help but worry. I enjoy my monthly reassurance.
