I started loestrin 24 fe for the first time and took 6 pills and had unprotected sex! Did the pills become active during this time?
they say your okay after 7 days of taking the pill.
i was told that it takes between 3 and four weeks for BC to become effective
Some say a week is plenty, others say to use alternate protection for a month. I always went by the later. Rather be safe than sorry.
