New Job

Kelly
I just applied for a new job took almost a month to get an interview I've had 2 previous miscarriages and never made it past 10weeks I am not 11weeks and 4 days I had my interview right at 11weeks the person who interviewed me asked me if there anything she should know. I chose not to tell her specially because of my previous miscarriages, it usually takes 2 months for all the hired paperwork for this job so by them I'll be around 16-20 weeks I feel bad not stating that I am pregnant by the time I start working I'll be showing idk if I should call her back and let her know that I am pregnant before I start working 😕 I plan on going back to work after 3-months off (this company lets you take 1 extended leave of 3 months without pay a year so that's what I want but I still feel bad 
Should I call her back and let her know?
