"i took this one pill the next morning after sex. i woke up shaking and scared because it was a one night stand. i didn&#039;t fully trust him when he said he pulled out even tho i saw him cum when he did pull out. so i couldn&#039;t take the chances. i decided to run to my walgreens and get one. it was expensive. but works. it&#039;s over the counter and the staff is discrete. they will most likely be in the feminine care isle or with the condemns. i had gotten my period about two weeks before so i wasent expecting it for another two weeks. i took it in the morning and didn&#039;t feel any symptoms. a couple days later maybe a week i got my period!!! i&#039;m not pregnant. the cramps with my period however. we&#039;re painful.they were the worst moral. this pill works"
