"i was one of the few people who suffered from anxiety because they weren&#039;t sure if this pill was effective. let me tell you, i am the worst with overthinking and i know what it feels like to be unsure. this pill really does work. plan b was something i always heard about but never thought i needed until one night of great sex ended with a condom that slipped off. we were both drunk and unaware of what had happened so to be safe, i decided to take the pill 6 hours after the accident. i keep track of my period dates and my last period was on the 21st. i took the pill on the 7th of the next month. i suffered some side effects like headaches, back pain and cramps 2 days before my period. it actually came 5 days early and it just finished today!"
