risk of me and my unborn child

Hello i was married at 2015. My husband working in central govt.Its was arya samaj marriage because my husband's parents was not agreed on that time. My husband now lives in his hometown and before that he lived with me. Now i am pregnant. Issue is my husband wants to stay with his family in hometown. But he is not support me in financial. He denied to give me any money. Point is who bear my expenses and my baby expense if i leave my job and stay with his family. As per the law 25% his salary gives to me as maintaince then how come i bear my expenses in 12k to 15k, as my earning now 30k monthly. Who bear my remaining expenses.His family always saying this is not yours house,will throw your laugage outside. And they already out my husband name in their house property. Now his family force me to come on their home,and they force me to dna test for my unborn baby. His family behaved is very bad for me.even its a life risk for me n my baby. My husband already give some medicine for unwanted pregency,also this pregency he want to destroy. Please advise.
