No, it's not your hormones. You have crappy friends. (Sorry to be blunt.) They are perfectly happy to dump work on you, but they can't be bothered to do something nice for you.
PLEASE, let go of your responsibilities now. What will happen is that all of a sudden, you'll end up in labor and they will say, "Why didn't you finish 'x'? We were counting on that. Well, can't you call people from the hospital? How about when the baby is asleep? I'm too busy, I can't do it for you!"
Then you will want to throw your bedpan at them.
No more handling, covering. No more. Turn over everything. And if one of your friends comes to see you, if you get ONE little chance to say it, no matter how little the chance, go ahead and SAY how disappointed you are that a shower wes mentioned, and then no one gave you one.
I really mean it.
