Hi I'm 19 years old and im on a patch and had sex 6 days after being on the pacth in the morning. I haven't had my period yet and I usually do when my bf has cumed in me. He cumed in me twich that day which does sound bad n the only thing I notice is my niples there more brown. Can this mean I'm pregnant? Next Thursday well be a free week off the patch but when I was on birth control pills I always had my time of the month when it happened.
