Pure exhaustion!!!!

I'm 26+2 today and for the past 3-4 days I have been sooooo exhausted. I feel like I get a good nights sleep (besides the getting up to pee 3-4 times a night) but small little tasks throughout the day just wear me out so quickly! All I really want to do is just sit on the recliner all day and rest. Is anyone else experiencing this right now?? I just want my energy back :-/
