Possibility of being pregnant?

Hello Ladies.

Here is my question to you all. So normally my birth control method is the pill. Anywho, at the beginning of this month I had just finished my period, and due to a mess up at the pharmacy I wasn't able to get my birth control on time. It was 4 or 5 days after my period finished when I finally got my birth control, so I started the first pill and the same day me and my fiance had sex. We didn't use a condom and he did ejaculate inside of me. How high of a chance is there that I may be pregnant? It's been two weeks since this happened so I have a little while longer before my period is supposed to come. Also I haven't noticed any signs or anything, I imagine it would be too early for that. I have been extremely moody lately but that could just be me. What do you guys think? How high are the odds or chances of me being pregnant?
