is it ok to work while your pregnant i work at a pizza resturaunt

It is perfectly ok to work while pregnant.  I would tell my employer right away though, because if you are working and are constantly going to the bathroom because of morning sickness then your employer may get mad unless you let them know what is going on.  If you aren't having any problems then I say go for it.  I myself with my second son worked in a pizza place.  Don't do any heavy lifting or any stretching.  Another reason why you should let your employer know as soon as possible, because yes they will give you some slack on some things.  Are you one of the ones who prepares the food or does the delivering?  If you are a delivery person then it would be better if they had you just in the restaurant instead of delivering because you sometimes have to carry a lot of food items.   I hope that this helped at all.
