Wrongful Termination

I'm working with present company since last 10 months in Gurgaon. Yesterday,, all of sudden my Manager called me and 4 more Junior employees and said we need to resign as company is going through cash stress, did not informed in-person which caused a mental harassment as well, and said that I would be required to resign & then relieved from my job by July end citing reason that Company is not doing good. Presently i'm in third month of pregnancy & its quite unlikely for me to search new job and work in new organisation. It is also surprising to notice that I was asked for resignation soon after I had informed about pregnancy to my reporting officer for information as it was essential for me to inform my reporting officer. But asking to resign was least expected and that too in front of other employees causing mental harrasment. In such situation can you advise suitable course of action. I also denied resigning but still they are forcing me to resign on immediate basis even after telling about the loss which i would incur for being jobless. Can you suggest what recourse do I have as per Indian Laws?
