"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&#039;all everything will just be fine. try not to stress!"
