Heard the heartbeat again!

So today I had another appointment, which took an hour and a half to get through, but I heard the heart beat again! I think the baby was playing hide & go seek because it took them awhile to find it, but all is well. The doctor said all of my lab work has come back positive, and I'm feeling great. I go back again in 4 weeks on March 24th. Tomorrow I'm actually going to see my sister in law's mother at the hospital for an ultrasound! It's been 5 weeks so I'm anxious to see how baby has grown. I'm not sure that she can give me a picture or not, but I'll let everyone know how that goes! I'm also looking into renting an at-home doppler machine, where you can listen to the baby's heartbeat right at home! You can rent them from month to month because they're very expensive to buy. So I want to get one for 3 months - that way we can listen to the baby's heart beat while I'm only going to the doctor every 4 weeks, and they don't do ultrasounds often. Plus, Adam has a hard time getting off of work to come with me and I think it would be very special to be able to lay in bed at night and hear the heart beat together!
