does anyone else hate their SO?

I've been pretty good with my mood since being pregnant but like now he just said something to me that I think he's kind of being a dick about but maybe I'm over reacting but it just set me off that I'm crying my eyes out and I like literally hate him now. And it's over something small! This has happened maybe a few times but I can't remember but I think this has been the worst that I've felt this way.
