I hate the question, when are you having a baby??

Ok I'm officially tired of this question being asked and feel that if another person ask me that, I'm liable to spazz out! This week at work really topped it for me. Every day almost the same girl (with no kids) always ask, when are you & your s/o having kids? So this day they decided to get a little personal and ask are you on BC or do y'all use condoms? I said, that's private why would you ask someone that? Then I said no we don't use condoms and the other girl said why aren't you getting pregnant then? I said yes I'm on birth control (I'm really not) But I have PCOS & have been TTC for 3+ years. I'm a private person & don't discuss my personal life with coworkers. And I have to see these people every day!!!😫 I don't know how much more I can take..... What are your thoughts?? Please whisper a prayer for me that I get another job & a bfp soon...
