So I took the birth control pill for one cycle and after having bad break outs and bad mood swings I decided to finish the pack and then stop. My first period off the pill should have started 4 days ago based off of a 28 day cycle. I was wondering if coming off the pull after a month of being on it could cause my period to be late? I have sex on December the 2 but it was with a comdom and it didn't break so chance of pregnancy is super low.
