Can Somebody Help Me

Ok guys . AF isn't due until the 9th right ; but lately for about 4 days now I've been having milky white discharge w|no odor & ive been having like little cramps that will come and go nothing hurtful or anything plus this has been going on for 2 days now every time I eat something I get nausea like it's gonna come back up & I've been craving a lot of sweets & I hate sweets . Could this b a sign of pregnancy or am I just losing my mind
