Very early symptoms?

I had what I think is implantation bleeding on the 17th of Dec. I haven't experienced any really harsh pregnancy symptoms though. I'm definitely bloated, light cramps, and feeling of fullness in my breasts. I had a bit of nausea but it could have been just a weak stomach. I was wondering how many of you would say I should be experiencing more by now? Am I getting my hopes up? BTW AF is due tomorrow...
