"i had sex with my boyfriend for the first time on november 28 around 10:30 at night, i wasn&#039;t able to buy plan b until the following tuesday which was about 63 hours later, it is now 6 days later and my period isn&#039;t supposed to come in until 3 more days, but i have to say, so far it&#039;s been a miserable experience. i&#039;ve had extreme cramps and bloating and a little bit of constipation. i don&#039;t know if it&#039;s from me stressing out so much or it&#039;s still from the side effects. hopefully this works."
