Oh ladies
Whilst I have never felt like what you describe during pregnancy (DH is very supportive and if he sees me not doing stuff/moaning he just gives me what I ask for and picks up the slack), I had an awful period at the start of this cycle, I was very depressed for two weeks, basically due to hormone imbalance I guess, as I was fine once I started taking my vitamins again.
During this time I didn't do anything useful, I fed the kids and looked after them but I cooked a couple of meals, didn't do any washing up/laundry/cleaning. He knows now just to work hard and that I'll come out of it and I'm very grateful.
However, after my last (our first) I got a bit of an OH aversion. I didn't want to be cuddled/touched as I was in almost constant contact with the baby or toddler or both! And he decided to pick that as an excellent time to quit smoking (which he managed yay) so we were anxious and stressy and on top of each other. Any harsh word and I was crying, any touch I was recoiling.
It was a horrible time emotionally, very intense - and all the same hormones are likely responsible that are causing your friction.
And omg any women who said she wasn't tired in her pregnancy - particularly in first tri - is highly likely to be lying!!
I had naps all the time in my first pregnancy and took them when my toddler slept in my second. Genuinely wondering how I will cope as DS2 barely naps now, and when he does the big one is usually here!
