Pregnant discrimination

Anyone facing pregnant discrimination in workplace? My contract ending with (agency working for MOM) and was not renewed due to pregnancy. But it was contract role and nothing I can do... I gotten another job offer as telesales executive in a MNC (Insurance company). Gd basic + Comm.. However after accepting the job offered via email, I informed them I’m pregnant b4 start work ( and b4 sign offer letter). The job offer was retracted due to “safety and health” concern as I’m already 5 months pregnant. Was loss and disappointed. Loss of income during this period of time.
