MY BOSS told me...

Everyone at my job is laid off and will be getting unemployment due to the Coronavirus. My boss sent out a group chat saying most people won’t be re hired after. I ask her will I be hired back she said sure I will only have you at the register because you pregnant I said okay. Today she sent me and text basically saying she won’t be taking me back... long story short I called her and ask her what changed ? we spoke about this Wednesday. “ in my mind I thought I was going to re hire you . I said what in your mind? Your verbally told me this so I’m confused. She stutters and say well I don’t know my budget and plus I would want someone who can do enough hours and who can lift heavy stuff. I said what now your discriminating me? Thanks and I hung up on her. “ she sent me a text saying FYI your pregnant you shouldn’t be lifting anything... etc. how ever there’s NOTHING Heavy. We work with 65% men so I was ultra confused. I feel violated. What should I do???
