"i had protected sex on april 6th and the condom broke. he came inside of me, entirely. i have a very irregular period and can go up to 4 months without having one. so it&#039;s very difficult to know when i ovulate or when i should start. i freaked out and bought plan b almost an hour after we had sex, i took it immediately and began to read reviews about it. i read reviews saying if you were over 170-175 pounds plan b would not work for you. but i am 210 pounds and on april 15 i started my period. please, i&#039;m telling you, do not stress. it only makes everything worse and can even delay your period that much longer. i was a lot more emotional before starting my period, and when it did start my cramps were almost unbearable. just relax! it works!"
