Q: How long doe yaz flex take to be affective ?

Doctor

A:   Hi,
Thanks for the query.

I understand your concern.
Yaz flex is a combined oral contraceptive pill which is having the facility to flex your dates of withdrawal bleeding.
If you start the pills during your period of menstruation, it will start giving protection from the first pill itself.
If you start the pills in the middle of the cycle, better to use an additional method of contraception like condoms for two weeks.

Take care.
