Pregnant?

My boyfriend accidently came in me the day I ovulated. This was about 5 or so days ago. The past 2 days I've been having the worst cramps ever and today my breasts have been so sore. I've also been really tired and about 2 or 3 days ago I was feeling ridiculously nauseas all day but never puked or anything. I know I won't know until I test after my missed period but I just want to know what everyone thinks.
