Being pregnant in the workplace....

Heather
I am a manager at a retail establishment, for most of my pregnancy I have maintained the same level of activities other then moving heavy objects.
Repeatly during my pregnant one other manager continues to make random comments about what I can and can't do. She even questioned me as to why my doctor made my weight restriction 20 lbs (pushing/pulling/lifting). After questioning me about it she went to my personal manager and asked to see documentation on it. I was about 25 weeks pregnant at that time. 
Now I am 37w1d and yesterday she told another associate to ask me to stand outside while a truck was being unloaded (a manager has to stand at the opened gate). I responded to that associate by telling him I could not stand outside in the sun for an hour in 95 degree weather and he would have to find someone else. I then communicated this with the same manager who has been making these comments during my pregnancy.
Here's the kicker-this manager is a woman. She doesn't have any children, but still she's a woman and I would've hoped she'd have some type of respect. 
I have went to my store manager about different things she's said and done through out my pregnancy. I let yesterday slide off my back because my last day is Friday and I'll be on maternity leave.
I'm just wondering if anyone else is experiencing things like this at work. With a male or female mgr. I've had a great pregnancy, but when you already feel like you're pulling less then your own weight at work because you're pregnant, and then someone acts like an asshole to you because of it, it can crush your spirit.
Anyone else?...
