Husband having sympathy symptoms??

My husband has anger issues, and can snap easily, however, he’s on medication and since starting the meds, he is a much nicer and easy going person. However, since I’ve gotten pregnant, I’ve honestly been acting the same towards him, at least I feel like I am. He says otherwise, he says I’m more mean to him and that I don’t know how to play.

But I really am playing the same we always have and my husband has just recently became so sensitive and he’s back to having the anger issues and he hasn’t stopped his meds.

Like yesterday, we were driving 3hrs away to the river to see my family and we fought about something super stupid and I ended it saying “it’s okay, it’s whatever.” Honestly just letting things go because it was stupid and my husband straight up called me a liar. He proceeded to call me other things and tell me to grow up when I was literally not saying a word and I tried to explain to him how I genuinely just let it go, that I mean no malice. He proceeded to scoff and act an ass of himself.

He has since apologized. But he’s been fighting with me over silly minute things so much and often. Like could it be the pregnancy? I feel like I currently have to tip toe around him when I usually don’t have to. This is our second baby.
