Emergency Contraception And Breastfeeding Question About Emergency Contraception?

Question About Emergency Contraception? - emergency contraception and breastfeeding

I took Plan B before 28 days and have not received my period. The site says that, if not seek out this is the case within 21 days of a doctor. BUT, I did not waste my time in 8 months anyway (because I am breastfeeding), it is normal that the pills did not start my period? Or if the pills have made my cycle start?
I will not be overly dramatized, and losing money by the doctor, which is nothing.
