Help am I pregnant?? What chance is there?!

Hey I've had some signs of pregnancy 
Sickness in the morning? Not being sick but sometimes heaving 
Sometimes constipation 
A bit sore boobs 
A bit of a darker colour 
Frequently peeing 
Back ache 
Stomach pain
Pains in my belly 
Pains left side below my ribs and right 
I had sex few days after my last period and he kept coming down there and I had sex on Halloween all with no condom and he didn't pull out! What chance is there and I'm a day late I think for my period
