"the condom broke and by time we both noticed it was already too late . roughly 10 hours after the incident i took plan b one step. i didn&#039;t really experience any side affects until the next morning i was cramping and had a bit of nausea . the incident happened about 2 1/2 weeks ago i took about 6 pregnancy test . they all came back negative . a part of me says the pill worked but another part still thinks it didn&#039;t . i sorta would recommended plan b . and just so y&#039;all know i am overweight . so i believe weight has nothing to do with the effectiveness"
