Anyone a pregnant waitress/bartender

Anyone else pregnant and working in a restaurant? I make very good money where I am and love what I make for the few hours I put in, but how did you go about it? Did you stop lifting heavy things? When did you tell your boss? What did customers say to you? 
Also, I will have a very good degree by the time baby is here and was wondering if I should try to find a salary job or not? At my current job I can make my own schedule, work very few hours, and still do well financially which seems like a nice combination for a family. I don't know if there is a part time job I could get that pays better and still offers those things.
Any insight is appreciated thank you
