Mental harassment & dowry demand by in laws

I was married 6 months ago. 15-20days were very happy but after that my husband said I don't like you I married you just because of your salary. In these 6 months my parents and my husband family had sat n number of times, issue was my husband & mother in law said we don't want you in our House, get out of our house. They wanted me to finance 8 lakhs car for them & also give my all salary to them. I am pregnant and they don't take me to doctor also , saying delivery will be at home. They had already thrown me out of house once after 2 months of marriage. Now again I am at my mother's house . A week ago there was meeting for settling differences but my in laws used abusive language and physical attack on my parents & went to out of my mother's house. On very next day I decided to go to police station, I was ready to go to police that once again in laws asked sorry for their behavior that this will not happen again , we want you to take you home. But because of my health issues I was not able to go with them. But this week has shown that they are still the same, they played this game of sorry because I demanded divorce from my husband. My gold jewelry was with my mother in law & they told a lie that robbery happened at home in this week & all jewelry was looted. They had not filed a police complaint of this robbery also. a bjp women leader is helping them who is threatening me. What remedies are available to me, I want divorce and my money which I have spent in marriage, gold back. I am ready to take care of coming child but I just wanted my hard earned money spent in marriage & divorce. Now I'm not in a position to go to police as stress has affected my health , my gyne has advised me complete bed rest, I am not in position to move also not sure up-to what time but may be till delivery after 3 months.
