Too Early to be awake!!!!

Well as most of you know I haven't been sleeping very well since thursday night. I have had a cold and then on top of it I think I am a little anxious about everything. Well I know that my baby girl is extremely active and usually moves up a storm, but the last two days I haven't been feeling her as much and I tried to make sure that I wasn't just missing it so I was sitting here after Mom left and was trying to relax and get her to move a little since I hadn't really felt her but once yesterday. Well she never moved so I got Jason to call the Dr and we went on to the hospital and hooked up to a fetal monitor for a "non stress test" on Olivia, she was fine as far as her heart beat, she moved a few times according to the monitor but I only felt her once which is still strange to me since normally she is even more active when I lay down on my side. My Blood pressure was surprisingly low, 122/66 at one point...Strange since I was nervous about eveything. Jason asked if me not sleeping might have something to do with her not moving, the nurse said no but it might have something to do with my perception of the baby, I might not noticed her as much because I am so tired. Well the Dr gave me Ambien, you know that pill that is supposed to knock you out for 8-9 hours, guess what it worked at first but look what time it is, 4:30 and I am up doing this..... I have prayed about this and I need ya'll to pray for me as well. I can't go on like this with no sleep. It is not good for me or Olivia. I don't know what else to do.
