How high do you think my chances are of being pregnant?

I haven't been on bc since March. My last period started on the 14th of June, and my fiance and I had unprotected the 27-29. I know its too early to tell, and I will take a test when I get closer to when my period is supposed to be. We arent trying to have a baby, but we arent not trying either. I'm also a very impatient person and the anticipation is killing me! Any feedback would be much appreciated!
