18 weeks and an ultrasound

I can't believe this pregnancy is almost to the midway point!  I was nervous and excited at the same time to have an ultrasound.  It was such a relief to see a healthy baby!  The heart rate was 144 bpm.  I was able to see one of the arms and amazed at the bone structure that you can see.  Such a big change from the last ultrasound!  The baby didn't want to move a lot and was in a weird position so we will have another ultrasound at my next appointment to check out my low placenta, the baby's heart, and the baby's face.  Maybe he or she will cooperate next time.  :)
