This is my first month on bc. Tomorrow april 19 will be the frist day of placebo pills. When should i expect my period to come? And if i have sex during this week, am i still protected by the bc? I should mention back in March 21 i took plan b because of a condom slip. So should i still expect my period to come this week or will it be delayed because of plan b? I'm on Reclipsen Birth cocontrol and took plan b within 12 hours of the accident.
