pregnancy signs.

So right now my boobs have been hurting for about a week, I've been off and on nauseous for the past 3ish days, I've been having slight cramps and I've been peeing a lot more than usual and I've also been eating more without feeling very full, Plus I had some discharge that about a week and a half ago that was thick and creamy, almost gummy like. I know the only sure fire way to know is to take a test, but is there a possibility I could be pregnant?
