I have been taking birth control for the past 5 years and haven’t missed a pill (taken some late by a couple hours). I had my period July 4-7 and had intercourse on July 7th. We used a condom and the pull out method. I am pretty sure the condom didn’t break but I do not know for certain. I was given the same dosage of birth control but a different brand at the beginning of July. I am not experiencing lower abdominal cramping and breast tenderness. My aerolas seem to be a tad darker but I dont know for certain. I am due for my period sometime next week. I know I might be freaking out but should I be concerned about pregnancy?
