Hello,
Thank you for asking at HCM.
Norlevo is a hormone that is used as
plan B (emergency
contraception)and that sometimes women using it might get bleeding. Up to 50 % of women using it might experience this so it is usual.
What I would say is:
1. changes in menstrual bleeding is often after use of Norlevo
2. You would expect the next period by calculation of the dates from the last bleeding episode (the bleeding after taking Norlevo) not the dates you would expect it before you had used Norlevo
3. emergency contraception is not recommended to be used as the routine continuous mode of contraception.
4. The more often you use it the more likely irregular bleeding is expected to happen due to
hormonal changes it induces
5. Speak with your doctor about the most indicated contraception method in your case so you can have regular birth control measures and not just sporadic ones as emergency contraception.
6. If you have regular periods generally you can also learn of the normal menstrual cycle and try to predict the time of ovulation and be more careful of
unprotected intercourse at that time. Condoms can be used also and no prescription needed but for oral contraception you will need prescription.
Hope this is helpful to you and answers to your question
Best regards,
