I really doubt you are pregnant. Condoms fail but you almost always notice that! Rips are big and messy. I'm guessing you are just late. This happens to everyone even if it hasn't to you before now. Things that make us late include changes in routine, stress, illness, losing or gaining weight, or just a shift in our hormones. Early pregnancy really doesn't have much in ways of real symptoms. You can test to be sure but again, doubt you are pregnant with proper condom usage.
