I need help

Ever since the moment I found out I was pregnant it seems like me and my mother are not getting along. We have been arguing almost everyday over really petty stuff. But today was horrifying and almost got violent I really felt sick to my stomach as we are arguing. It's stressful and I'm really getting tired of it. When I am avoiding her she keeps nit picking until it really pisses me off. I am 7 weeks and 5 days. This is not good for me or the baby I really don't know what to do.
