Your pill is exactly like the pills we have in the US, except it is a different brand name.

YOU can use PLAN B/Postinor , or emergency contraception...
It is safe to use with regular BC pills, and would give you added peace of mind.

With Microgynon, if you have missed ONE or TWO pills, you will still be protected against pregnancy and you don't need to use extra contraception. Take the last pill you missed as soon as you remember, then continue taking your pills, one every day, as normal.
