bad fight with husband

So we hardly every fight. And if we do, we get over in in like 30 seconds cuz it's never a big deal so this is why probably what happened last night is bothering me so much. Im 10 weeks pregnant, and get tired very easily. So at 10 pm we are laying down in bed, hes watching YouTube on the laptop and I fell asleep. fairly normal for us. then I randomly wake up around 2am to go to the restroom and I thought I saw him change apps when i looked over. I asked him what he was doing and why he changed apps so fast. he said he was turning down the brightness since I was waking up and it's dark in the room. I technically dont know if he changed apps or not, all I know is the screen flashed, so he might have adjusted brightness. okay anyways I still got upset, maybe its these hormones but I didnt cuddle with him all night. so now its 5 am and i woke up in a big puddle. i was like omg the dog peed!! we have a mini yorkie and she sometimes peed in her sleep. I'm not sure if its bladder issues or what because she is 1. I have a suspicion he didnt take her outside before he went to bed. he said he did but I dont believe it. we usually get up and take her out around 5 anyways but today was the 3 day weekend so that might be the cause. anyways, i took off all the sheets and the mattress protector while I made him go walk her. it's still dark out and our neighborhood is a little unsafe. I put the baking soda on the mattress to help absorb it and 10 minutes later I hear my dog screaming from downstairs. I though he put her in her kennel which was fine by me but apparently out of anger he kind of pushed her on the stairs and I guess she hurt her foot or something. I was sitting on the ground and just bawling my eyes out as i held her while she cried. then he just went upstairs back to bed all angry with no compassion. we are both very against hurting animals and I dont think he meant to hurt her. we do smack her butt when she has an accident but she never cries this much. usually it's one cry that's it. anyways my dog is fine now I'm downstairs on the couch just finished crying so I can type this and he is asleep. we had plans to go on a date today and now i dont want anything to do with him today. ladies what do you think i should do? should i wait for him to apologize? what should I do because we are both home today? should I just go out shopping or something? thank you. it might not seem like much but to me this is a lot because like I said, we NEVER fight.
