Weird boss

My boss is not a bad person to begin with. But somehow my working experience get weirder and weirder everyday He goes around telling majority of our suppliers that I’m pregnant when I don’t have the intention to tell any of them. Cos I don’t see a need. And I think it’s not morally right to tell others about staff’s personal life. I don’t personally know all these suppliers and I don’t deal with them often/directly. Then when supplier has illogical request like resending the same email (which was already done), my boss simply blames it on my pregnancy telling those suppliers “bcos she’s pregnant, it’s unavoidable that she will be forgetful and makes mistakes.” Like Whhuutt?!?! Is it even fair that he blames it on my pregnancy? I tried to tell him what really happened regarding the email thing but he didn’t want to listen. And he’s always making remarks like “it’s ok to forget, you are pregnant” or “I try not to ask rely on you for the data bcos you are pregnant” Somehow he just made me feel that being pregnant was a mistake and that I will definitely compromise my work. I feel so upset. I want to work so that I can be financially independent but he’s making it tough. The mental stress is real.
