Vent!!!

So today my step mom asks me if I was really pregnant and she says she asks because as she says Im not showing any symptoms of being pregnant. Now my problem is not what she asked but the way that she asked it. Like she was insinuating that I am lying about being pregnant. Like why would I lie about something so serious like that. On top of that tell my father that I am pregnant my firat day moving with him. I'm so confused. Now because I'm not puking my guts out or sleeping all day or eating up everything its a question of me being pregnant. I'm really confused. I have a 1 year old son. I can't sleep all day of course. And she knows everyday I'm nauseous 24/7 to where I barely be wanting to eat. Idk I guess it just really bothered me because she's acting like im lying or something. I guess if she was around me when I was pregnant with my son she definitely wouldn't have believed I was pregnant because I didn't have symptoms with him for the absolute longest. Please tell me if I'm being overly sensitive or not. Idk that just bothers me
