Massive argument with SO

Sat in the house alone because he left. We had a massive argument. Just think this pregnancy is putting a lot of pressure on us both. I'm struggling at work with tiredness and sickness. And he's worrying because he's out of work. Just wish I felt supported and I wish he understood he's not the only one suffering. I think my hormones are making me too honest. Does anyone else find they are arguing with their husbands / partners more since pregnant?
