Welcome to HCM,
You should have started microgynon
pill from first day of ovulation.
You had sex on the day, just after your period. The day just after period, is generally 4th day of menstrual cycle, and it is generally safe regarding pregnancy
contains 30mg of ulipristal acetate. Lifespan of sperm in female genital tract can be up to 5 days, and IllaOne delays ovulation up to 5 days, thus prevent fertilization of egg.
(i) As you had sex during safe period and taken EllaOne also wthin 72 hours, you should not be pregnant.
(ii) Your doctors advice seems proper.
(iii) You can wait for withdrawal bleeding and start a fresh pack of microgynon from first day of period.
