losing appetite again?

I know it's Valentine's day today and I do have plan for the evening. The problem was since I woke up in the morning, i couldn't seem to have appetite for anything. I had to spend at least half an hour to finish a tiny meal. I even had a little morning sickness, at 7-month pregnant, yes. This is bad. I wouldn't wanna ruin this day's plan cos it will be the first for our family. But hey! at least my baby still kept all the kicking and whatever she was doing in there. Any thought anyone?
