Is Pregnancy Possible Through Pre-ejaculatory Fluid?

I had unprotected sex 2 weeks ago. He didn t cum inside of me but there could have been pre cum. I know this becasue I went down on him after sex and he came a few minutes after. We were both drunk if that helps. I am now 2 days late for my period, I have cravings for carbs, crunchy, salty foods, I m peeing more than usual, my moods are strong, and the sides of my breasts are sore when I press them. These are usually how I am when I m about to get my period but not as rough. I had discharge a few days ago. I ve also been under stress from a week of exams the past week and I m anxious that I could be pregnant. I would like to know the chances if I could be pregnant?
