I dont think you are pregnant even though. This may vary on some girls because some girls never get it while they are on the pills.. Or some girls do actually... So dont worry about it. If you are scared and worried, take a test (uif you have any sign of pregnancy). I hope I helped

I have been on yasmin 4 mos now and have had sore breasts etc lik eyou have been expereinceing. I usually get my period on the 3rd day of placebos, although I tried to reschedule my period for next month by starting a new pack immediately after reaching the placebos ( did not take placebos). I did not get my period and I am hoping that it comes one week earlier than previously scheduled so I can enjoy mexico!
