Pregnant and getting depressed

I'm pregnant still living with my mother. Everything is working out fine except not. I should be moving in with my boyfriend in January and still haven't found a home. He is being super difficult in agreeing to a home. I can't do anything else cause I want him to be 100 per cent all in when moving in. And all the time he comes to visit me on weekends we argue and argue because he thinks my mother controls everything but I don't think so, he should thank her for all the support cause I still live with her this wasn't planned and so when we argue he yells and is awful to me and I'm 6 months pregnant and I get so nervous and so upset that my belly starts hurting and I get even more nervous because I feel bad for the baby if she feels it. It's awful and I'm starting to dought all this... I'm getting desperate. He's not mean or anything and he loves me but it's as if he can't see/acknowledge that I'm pregnant I'm emotional and that the baby hears and feels everything.. are there any pills that can relieve this stress without harming the baby? Anyone like me like crying all the time? Super scared that I'm harming the baby.
