Is there a high chance I'm pregnant?

My period is 2 days late and I had sex 3 times (once during ovulation) this month (unprotected but no ejaculation) and we made sure we urinated and showered many times between all the times we did it.
I don't have any symptoms other then really light cramping and some urination. I've had cramps ever since my period was due but lately I've been so stressed with being pregnant and eating badly. My sleeping schedule is all over the place and I've been doing a lot of activities this summer. 
Is there a big chance I'm pregnant? (Yes ik I should of got protection) and I'm taking a test tomorow to see if it's okay
