Stuck in the hospital

I went in for a check-up today and they found that the amount of amniotic fluid around the baby was a little low. The doctor decided to admit me for the day and overnight for IV fluids and fetal monitoring. There were a few contractions but so far everything seems to be ok. They said the baby is fine and weighs 4 pounds, 10 oz right now. They are going to re-check the ultrasound in the am to see if the amniotic fluid level has improved and probably send me home after that and I will probably be on bedrest for a couple days.
