I should be expecting my period tomorrow, however i am experiencing other pregnancy symptoms and i am not sure if they are pms. can a discharge that s?

Can't tell: You do not state what the other symptoms are and why they would be confused with pms. If your period were due tomorrow, at best you would be only 1-2 weeks pregnant so i don't know what symptoms you are referring to this early in a pregnancy. Your reference to a discharge is incomplete and can't be answered at this time.

See what happens: tomorrow. If you have a normal period than you aren't pregnant. If you don't then take a home pregnancy test.
