Pregnancy hormones and mother in law

So my mother in law has come to visit my fiancé and I. We live in a one bedroom apartment so we’re already limited on space. She’s staying with us for 4 days. Well, a couple weeks ago I found out I’m pregnant. Today I am 5w2d. So I have been feeling like absolute crap lately. Well I left work today quite a few hours early today, to come home to my mother in law and her friend asking me “you only work 4 hours a day?” Let me remind you, I work full time, am in 18 credit hours at school (which this week is my spring break), we just got a puppy, and my fiancé and i are both freaking out that I’m actually pregnant. I JUST WANTED A BREAK AWAY FROM EVERYTHING FOR ONE DAY. I don’t think she meant it in any type of way, but the way she said it and the way I perceived it made me so upset.
