So fucking grumpy... Sign of labor?

Erbear
So I'm 39/5 and I've been in such a bad mood the last two days. Some stuff has gone wrong, but I've had a ton of energy, decided to break out the skil saw and make shelves, which I heard are all signs of labor ( specific to the woman of course) but I'm so fucking cranky too. Like I can't even enjoy the last few days of pregnancy bc of it.

Anyone that's already had their babes, did you get super grumpy before labor?
