i'm not sure if weight is a factor with it. the only thing you can do is wait. i know it s*cks but...it's all you can do. if your period doesn't show up take an hpt.
ok...so i had an i pill...3 days back...my periods r to come on the 18th of next month...and im a bit obese...so...does tht give any chance for i-pill to fail???
if he touched his penis and went directly to your vagina yes there is a possibility. if he wiped his hands, washed his hands or anything in betwen then chances are you're not. if you take b/c daily then chances are you're not. if it was one pill (unless plan b) one day that won't do anything. wait until your period is due and if it's late take an hpt or get a blood test done.
