Opinions?

So according to this app I'm 1 day late. I usually start on the 3-4th so I feel like I'm actually a little later. Me and my SO have unprotected sex (pull out) regularly, a few times a week. For a week or so now I've been having light cramping in my lower stomach and my back. I'm always tired and I feel sick to my stomach a lot. I took a test maybe 3 days a go and it was negative. But alas my period still isn't here. Also this morning I had a white creamy discharge. Any tips? Should I just go get another test or wait it out a little longer?
