What happens when you take the second dose of plan b 3 to 4 hours late than 12 hours apart. So it Wilooks be 15 to 16 hours apart.
Looking at the studies done on the Princeton website, waiting 15-16 hours should not make a difference to the effectiveness of Plan B. If it was going to work, then it should still work.
I say 'if', because Plan B works by delaying your ovulation. If it is too late & you're already ovulating, then it is unlikely to be able to prevent pregnancy.
If you can tell me when your next period is/was due to start, & what date you had unprotected sex, & then what date you took the pill, I can probably give you a better idea.
