Am I pregnant

Briana • Great job,8 years with my bf, waiting to have kids
The other day.. 4 days ago to be exact, me and my bf were having sex(it was the first time in 3 weeks)and the condom broke. Upon realizing this, at 9 in the evening, we raced all over Stockton trying to find ANY open pharmacy. Fortunately we found one and bought the morning after pill. I took it immediately then went to bed. Unfortunately, I think I'm showing signs of being pregnant. My appetite is starting to decrease, I'm starting to get tired earlier, and today I started experiencing cramps, but I don't think I'm on my period yet.. Am I pregnant?
