Harassment by mother in law

I'm married a year ago. But me and my husband reside in Bangalore. Due to the pandemic we lost our job, so we decided to go to our in - laws - place. My mother in law has allowed us to live only for one month. After that she started harassing me about the dowry, jewellery. I handed over my jewellery to her and I left the house because of her torture. Later I claimed the jewellery. But she refused to give it back. Whenever we ask for the jewellery she creates a big issue and torturing me. Not allowing me in the kitchen to cook food, not allowing to touch any vessel,not even to do pooja. When my husband asks about it then she claims it as her home hence I follow the rules or else we have to leave the house. As I was in early pregnancy I couldn't fight against her also I couldn't bare the torture and harassment by her. Neither she is allowing us to reside nor returning the jewellery. Am planning to lodge a complaint against her. I would like to know about my rights in my in laws place.
