Is it okay to send a text message to tell the boss that I am pregnant?

Tell the boss that I can’t send text messages because I have sex. Your leader is your superior, and you should be polite and measured when speaking to your leader. If you are positive, such words are oral and are not suitable to be spoken to your leader. You can choose to explain that your nucleic acid test result is positive. If you choose to ask for leave by text message, it will appear less formal. You can choose to call and tell the reason for the leave to get approval.
