Am I?

I had sex on the last day of my predicted ovulation - hoping that glow is accurate even though every site says a different ov time. Also following my CM - which was seemingly pretty dry then. Sex With a condom. and he didnt cum. Its only been about three days and today I had a creamy discharge. And Im having cramps, but thinking that is due to the fact that he went pretty hard. How likely is it that I could be pregnant?
