Possible signs?

So I'm 3 DPO, or more, I'm not entirely sure when I ovulated. I know it was 3+ days ago. In the past few days I started getting cramps, like I start my period in a few days cramps, but my period isn't due for almost two weeks. I also started having a yellowish discharge. I keep getting very nauseous, and I'm extremely bloated. Has anyone else experienced anything like this. Could I be pregnant? With my last pregnancy I showed symptoms very very early so I'm thinking that I am pregnant again.
