Unprotected sex during ovulation.

Okay so pretty much I had unprotected sex with my partner 4-5 times during my ovulation week (Between the 30/12 - 5/1). 
Is it a high possibility that I may be pregnant? 
I don't think it's been long enough to be able to take a test though, my period is due in 7 days but my boobs have been very tender the last couple of days and I've been getting slight cramps for about a week.
