Pregnancy Insomnia

Why in the world can’t I sleep. This has been going on for a little over a week now, I’ve been getting up at midnight, 1am, 3am and not being able to go back to sleep. I’m so tired though! I haven’t been taking any naps during the day, I thought that might have been a problem. It didn’t help. Last night was particularly not a good night, I’ve been overly emotional and crying for no reason or blowing up at the smallest things. The end of this pregnancy is sure putting me through the ringer.
