I'm 21 weeks pregnant and for the past 3 days I've been unbearably tired..to the point I want to cry. About an hour after I wake up I want to go to sleep again and can't stay up any later than 930. Any ideas of what could be going on or is this just the wonderful result of my pregnancy? I didn't feel like this in my first pregnancy except during my 1st trimester. I just want to feel well rested 😭😭😭
