Project release related

Actually I'm new to TCS and don't know the policies much here.

I had taken Maternity leave for 6 weeks due to miscarriage that happened to me due to taking more stress in the project. From the start I had been asking my manager but he was given wfh and telling you had been selected for this project.

But in my team they are not supporting only for the coming office and many unnecessary things they are torching me.. i don't want to work in that kind of team.

My billing was there until March now it is showing until June. Don't know what to do for get released from the project.

Please suggest me..
