Mentally harassing by inlaws

I got married in Feb2016. My inlaws were against this marriage and didn't attend our marriage as well. After two years of our marriage they accepted our marriage and asked my husband to come back to their home. We shifted there in 2018 and start living there happily, i adjusted according to them, they conditioned so many things like stop working which is the biggest decision for me to quit my job. Then day by day my MIL started shouting on me. Treating me like a maid. She started mentally harassing me. One day i told them that iam pregnant. She suddenly saying to my husband that you both cannot stay here anymore. In every day my MIL harassed me and forced me to leave the house. As my MIL said that is her home. Now iam at my dad's place. And i want to make complaint against them. My parents are not enough capable to take care of me in pregnancy. My husband is also not staying with me. In this condition i need my husband, i need a home. Please tell me how i can make a complaint against my MIL. Also she is my step MIL. And she is doing all this to me. And even to my husband.
