Confessions of a 2nd time mom-to-be

It is 8:40 pm on a school night and my son should have had a bath and been put to bed an hour ago and yet I am letting him watch an only vaguely appropriate family movie (The River Rat) and yet I am too sick and bad mood and exhausted to move and just want to cry. And I am contemplating calling off work tomorrow.

I could handle bedtime but the tub needs cleaned and just the physical activity of that and doing bath seems impossible. Yet, I can't send him to school dirty - he was playing outside with the dog in the wet leaves and everything...

My husband isn't home and won't be anytime soon.

Will it be like this for 9 months or just the first trimester? I feel like a terrible mom. My first pregnancy I was never even sick.
