I was sick before I found out I was pregnant. It was actually an ER doc who suggested that my nausea and vomiting were morning sickness. Anyway, because of this I've been laying in bed a lot. I haven't been taking a lot of naps, just taking it easy.  For the past few nights I've been waking up and not getting very much sleep. I woke up at 3 this am and can't get back to sleep. Is this a pregnancy thing? I'm in my first trimester. Anyone else have this problem?
