need advice!

I am currently 2 days late for my period and I took a test this morning and it was negative but I've had a lot of discharge within the last 2 hours and it was egg white. I also have felt nauseous all week long and had light cramping for 2 days straight right before I was suppose to start. Does anyone have any advice on what I should do? I'm getting excited but I don't want to get my hopes up once again
