"do not stress out. i was in your position and i would re read reviews hoping for the best but thinking the worst, me and my boyfriend had sex and the condom broke, we took plan b about 15 minutes after, but it takes 10 minutes for the sperm to reach an egg. i was stressing out and thought i was pregnant but the faster you take it, the better. i am not pregnant :))) but do not stress out because that will delay your period. i searched up remedies on how to get periods if late and i drank a cup of warm milk before bed and the next morning my period started :) ( but you will get light bleeding at first which is normal.) i bled for 4 days and then went away and came back for about 8 days. rather have my period then be pregnant at 16."
