do you think the discrimination towards working and pregnant mothers at work are real in singapore?

Yes, I was asked to leave after I gave birth to my firstborn. One week after i return to work, I am placed under monitoring and 1 month later ask to go. Reason given by the company is not meeting KPI but I am the top performer of my department for the past few years even during my pregnancy. Called MOM for help but was told nothing can be done by them. Heard from some of my friends, they also encountered the same issue too; they were told no need to return to work after ML. One even lose her job promotion after she told her HR she was pregnant.
