Pregnant? Or too early?

I got my UID taken out 9/7 then got my period on 9/10, and according to the chart I ovulated 9/27, I had sex before during and after ovulation, and also last night because my CM seemed like the raw egg white so I figured why not. According to this my period is in 8 days. I have had some cramping, and been urinating constantly and have lots of strange food cravings. Would it be too soon to know if pregnant? Should I wait until the missed period? When I was on my iud I never got a period so I’m not sure what my cycle is like now off it.
