3 days late with AF early pregnancy symptoms?

So I’m three days late my period is extremely regular so three days is kinda a lot but I keep feeling like I’m going to start I’ve been having light cramps just like right before you start and I’ve had them since I was supposed to start, I’ve also been really dizzy specially when I stand up but I’ll randomly get dizzy just sitting on the couch. My nipples are also tender and my CM is clearish and stretchy, and some of its been white and kinda creamy. I wanted to have a baby that’s why I got off BC but not this soon I wanted to get pregnant by the end of this year, I’d be happy either way just wasn’t planning on this. Do you guys think I’m pregnant? I need help when do you think I should test? If anything I was just going to wait till this weekend and if I haven’t started then I’d test. Any advice?
