So I work in retail and I'm almost 17 weeks pregnant 
Almost everyone expects me to do heavy lifting like working on bulky pop or heavy top-stock. I'm only 5 ft 4 so stretching to high shelves is a struggle as it is on stools. Constantly getting backache also.
If I refuse or get someone else to grab the heavy things I get comments like "wouldn't it just be better if you quit?", "you never do any work", "what do you actually do when you come into work?"
(Topstock is the higher shelves that carry stock that won't go on lower shelves due to capacity)
My manager always assigns me to these tasks!
I am sick to death of having to explain to them over and over that I'm pregnant!!!! They are all men nobody understands, it frustrates me!
Sorry it's mainly more than a rant than anything, I can't wait to finally go on maternity leave!!!!
