no af symptoms

So I'm currently 10 dpo and af is expected in 4 days. I usually get bad cramps, bloating, and backaches for a week or two before af (since this is my first cycle charting, I'm not sure but I assume that these start from ovulation and continue until af). Well af is only four days away and I have none of these symptoms! I had them all for a week or so around ovulation time but now they've been gone for a few days. Usually at this point I'd be thinking I'm getting af any minute because the symptoms are all there and intense but this cycle I have nothing except occasional nausea (which could totally just be in my head) and boobs are a little sore. Every now and then I'll get the *tiniest* twinge of a cramp, but nothing strong enough to even consider a cramp. Has this happened to anyone before? Could I be pregnant or is this just wishful thinking? Don't want to take a test yet and get my hopes up for nothing :(
