I'm 19 turning 20 in April my due date is July 10 and this is my first pregnancy

Artavia • I'm 21 years young my baby boy Ashton was born on July 12 2016 💙👶🏽 #firsttimemom 💜 #milfstatus
I'm 5 weeks today and my stomach is two times the size it was before I got preggos so I'm showing fast and I think telling my managers today is best because I usually work in receiving where I lift heavy boxes and have to lift heavy merchandise on high tanks and crouch really low and reach really far to put merchandise on the bottom and it's very rapidly paced. Do you think it's too soon or perfect timing seeing that I found out on Tuesday that I was expecting?
