Dont understand

I have pcos and its hard for me to get pregnant, but since nov i have not missed my period. Its been late by a couple of days but it comes. I was suppose to get my period by the 14th of its been a week. Do you think there could be a possibility that im pregnant? I dont want to get my hopes up. I also sneeze n pee n having some type of liquid come down. I just dont understand i raised my hopes so much just for it not to be. Any suggestions.
