Levonorgestrel
"So me and my bf had unprotected sex June 6th and he did the pull out method but at the time I was very fertile so I was worried and took the plan b exactly 12 hours after. Trust me the two week wait is long and waiting for your cycle to start can be so stressful but plan b does work and I got my period on time. Well a day earlier. My period is really heavy which is a side effect of the pill. But trust me y'all everything will just be fine. Try not to stress!"
