Plan B One-Step
"On 2/8/16 I had sex and right after he realized that the condom broke. Like 30 to 45 minutes later I took the pill. I wasn't sure when the pill will make my period come simply because I just got off my period on the 6th or 7th. 2 weeks later I get my period and it was longer than usual because it was of the pill and it was medium-light. The pill worked but it messed up my already messed up period. But the sooner you take it the better. If you do it between 72 hours it's up to 89% effective and if you take it less than 24 hours it's up to 95% effective. I feel like it only doesn't work if you wait HOURS. So try to take it less than an hour after sex and you'll be fine."
