Could I already be pregnant?

Cecily

So my last period ended on the 22nd, and for the past few days I have had egg white cm, that’s really heavy, and I had sex on the 2nd and 3rd , my cm is now starting to lessen and get creamy, and I’m starting to have mild cramps, but my next period isn’t supposed to start for another week or so, could it be implantation cramps? Could I have ovulated so quickly?
