Well I'm a full time mail carrier for the USPS and was told to go see my dr. 
They basically no longer wants me working because I keep bringing back mail because of the load being too strenuous. 
I am currently 19 weeks and 6 days pregnant.
I go to the dr tomorrow and he will begin to fill out my light duty paper work.
The last I was told by my dr was that I can work 8 hours and it's even good for me to walk.
But it's a hassle and I just want all of this to be over with.
Before I got pregnant (with twins) I was energetic worked overtime and even did favors for management but I'm sure they don't remember my work ethic prior to me becoming pregnant.
What's going on at your job ladies please chime in... Just looking to hear others stories about these trying times for us all
