Increased arguing with partner?

Anyone else finding they are arguing more frequently with their partner? I’m feeling really frustrated. We were never like this before. Baby is six weeks now. I feel guilty when we argue in front of her. I know all the sleep deprivation and big life change doesn’t help. Just venting I guess. Feeling pretty defeated about our relationship right now. Sex hasn’t been working either for me. I got cleared by my OB but it was way too painful when we tried and now I don’t even want to.
