Discharge before period

My period is supposed to start tomorrowish and I uve been having some cramps but (sorry tmi)I've been having a clear to sometimes white discharge all week and i have gotten some moments of nausea. I did do a week of 150mg of Clomid and a shot of ovidrel two weeks ago so I'm not sure if this is normal or what. I don't know if I should take a pregnancy test or not because I'm not sure if I'm ready to be disappointed yet. Is this normal or should I wait a few more days to see if my period starts or not
