Ten Days Late... Am I pregnant?

I am fatigued, my boobs have gone up a size and I have a full ache just off to the right of my stomach at least once a day. My period is now ten days late and I have had unprotected sex a couple of times since then. I know I know it seems like "duh of course you are" but the reason I am questioning it is because 1 I am terrified of this happening 2 we have done it a few times without a condom, yet we made sure we stopped before he came... (😏 the did something else)
So I guess we were being stupid but we were still being kinda careful... what are the chances of me being pregnant?
