Needing some advice and to vent... 😖

Heather
I am 32 and have been TTC for 10 mo now with no luck. My co worker and her husband decided to try... And got pregnant on the very first try! Don't get me wrong I am very happy for her!! But.... She constantly complains about it and how she doesn't think she's ready and she knows how hard I've been trying!!! Now it's always showing me ultrasound pics and Yesterday she even went as far as rubbing my stomach and saying is there a baby in there yet?!!! I'm trying to keep my cool and not cause any problems in the work place but it's really getting to me... I go home and cry to my fiancé all the time. Idk what to do or how to handle this situation. Any advice would be helpful. And thanks for listening to my rant ..
