Not sure how I contribute

Denise • Have a energetic, smart and sweet 2-1/2 year old that's so much fun! Been married for 11 years. On my 3rd pregnancy.
I'm pretty sure it's mostly hormones talking, but that doesn't disregard the fact that I feel useless around my house. 
What started it: 
My husband said he was having a bad day yesterday. I've been really slacking on cleaning and laundry because I just feel like crap during this pregnancy. But I thought it'd be nice to have the house nice and clean for him when he got home. 
His response was that he doesn't care about a clean house. And I know in the past this meant "don't stress about it, just focus on the kid", but it stung a little. 
On top of it, he's going to a wedding with our son tomorrow. I decided to stay and work. I only work on Saturdays so I feel guilty taking off work. But, today I noticed that I don't have any appointments and offered to go with. 
His response "no you need to work". 
So I just feel like my efforts of SAHM are nothing to him and it's only worth anything if I make money. 
Sorry for the pity party. Thanks for listening.
