Trouble Sleeping

Hi! I'm 15 almost 16 weeks pregnant with my first now and last couple of days I have noticed that my sleeping is off. I'm not uncomfortable, not going to the bathroom a bunch (maybe once or twice, three at the absolute most and that isn't very often), I'm just not tired. I go to bed at a reasonable time at night (around 9-9:30, ten at lastest), but I just lay in bed for HOURS wide awake! Finally get to sleep (well after midnight!) and sleep until 9 or 10 am. Maybe have a short nap in the afternoon (30 min to an hour) and repeat. No matter what, I can't sleep! Not even tired! I keep logging and Glow is like "Women need lots of sleep in pregnancy!" And other "need more sleep" related advice. But I just can't sleep suddenly! Anyone else have this problem?
