Am I allowed to be grouchy?

Ok vent time.... Hubby and I bought our first house back in April and after renovations we moved in June. From June to August it was great he would chip in with the cleaning and we had a system... Then my brother passed away and we were never home etc because we were helping with the arrangements... I was depressed for some time and hubby was supportive. I finally was about to get up and do things and next we know we are pregnant! We were trying so it wasn't a shock. But after my brother's death the hubby hasn't been able to get back into his groove with helping around the house. He works 4pm to midnight and all he does all day is watch shows on Netflix. If I say anything he brings up that I didn't do this or that even though I'm the one who has been doing what I can especially feeling sick and having a horrible cold. Is it too much for me to ask him to do stuff? I just don't want to deal with his attitude. But it's getting ridiculous.
