How to handle harassment from in-laws after marriage and pregnancy?

I got married in December 2022. After the marriage, my sister-in-law and mother-in-law started harassing me, claiming they were unsatisfied with my maternal family regarding the marriage ceremony. They kept influencing my husband against me by feeding him wrong information about household chores and marriage rituals. This led to frequent arguments between my husband and me, often starting from 11-12 PM and lasting until 5-6 AM. Even during my pregnancy, they did not spare me, resulting in more mental agony and physical health deterioration. I delivered my baby at my maternal home, and since then, I have not visited my husband's home. My baby is now 4 months old. A few days ago, my husband and father-in-law came to my maternal home and started arguing with my family. I do not want to return to my husband’s home, nor do I want to face harassment from him or my in-laws, wherever I move with my baby. Please suggest what I should do in this situation.
