Am I okay?

I am 32+4 and today I just can't get out of bed. I've dealt with fatigue before but today I just feel achey and exhausted all over. I feel like I could sleep for days on end. My hips and back just ache. They're not hurting though. Is this what it gets like towards the end months? I feel so lazy! I haven't done anything out of the ordinary to warrant more exhaustion, in my opinion!
