My company wants to terminate me cause I’m pregnant

I informed my employer that I’m pregnant, and she’s a "Pinay teamleader in a remittance company in japan."

After learning about my pregnancy, she suggested that I leave the company, citing concerns that I may not be able to fulfill my duties in the long run since my job requires marketing outside.

She also mentioned that the father of my child is in the Navy, implying that I might decide to quit. Should I consider filing a case if they terminate me due to my pregnancy?
