I have a question. Everytime a male hears I'm expecting. He gives off this wired vybe like he is upset I'm expecting. Or either in shock. You guys understand what that means ? And dunt get why would you be in shocked. Like I'm not a freaking man. I'm a woman. ..... I have a womb.... I make eggs.... like why would you be shock I'm expecting? This is one reason I don't post my pregnancy on social media. Cause some people just give negative feedback. I swear I dunt get this act.
