pretend pregnancy

Can ur body pretend that ur pregnant like it wants a baby so it will bloats u up and give u cramps and make ur nipples spill milk cause I heard that can happen and I think it's happening to me rn. 
UPDATE:- I told my mum and she got mad because she didn't think it is and I told her some of the symptoms and she wants to take me to the doctor to get "checked". I don't want to so we have had a big blown up argument about it.
