If I take the Plan b pill today could it be a chance me not being pregnant? Or could it be 50/50 Now ?
Plan B is not as effective as regular hormonal birth control. It's simply worth a try in an emergency. Better than leaving it to chance. Lots of women become pregnant despite using it.
Plan B works by delaying your ovulation until the sperm leaves your body (up to a week). If you're already ovulating then it can't do that. You'd need one of the other methods of emergency contraception; either the other emergency pill called Ulipristal Acetate (Ella), or to have an IUD fitted by a doctor. Either of those things can be effective if done within 120 hours/5 days of the unprotected sex.
You have up to 72 hrs to use Plan B, but it's more likely to work the sooner you take it. Percentages would depend on where you are in your menstrual cycle.
