emergency contraception
"My boyfriend and I had sex and the condom broke. I'm normally on birth control but had an adverse reaction to  a new prescription and stopped. We immediately drove to Walgreens and bought Plan B One Step over the counter. I was frightened by the amount of side effects people mentioned in previous reviews. All I had was a light headache and I was tired, but these only lasted 1-2 days. My period started about 10 days after taking the pill (and about 3 days earlier than normal) and it is a very heavy flow, much heavier than normal (which is fine with me if it means I'm not pregnant.) Just give it time and try not to worry. It WILL work. $53 is DEFINITELY money well-spent"
