I had unpretected sex a little over a month ago. About 3 weeks ago I got my period but it was kind of different then normal. It lasted for 2 days. The first day I kind of spotted and it was a brownish pink color. I've also been sleeping and using the restroom a lot more then normal. Now the last couple days my breast are becoming sore. Is it possible I might be pregnant?? :confused:

Yes, it's possible. However you are now playing the waiting game. You need to wait to see if you get your next period. If you don't, take a test using first morning urine.
