I had unprotected sex two days ago,well almost 2 days ago, he didn't cum inside,but precum ,i just took plan b,what r the chances of being prego?

Low but possible: Precum has enough sperm in each drop to get you pregnant, not as much as the main load but enough.Plan B works in most cases when used as instructed, but sometimes doesn't.If this is your pattern for sex, it's just a matter of time until you get pregnant.Either have him not start until a condom is placed or find another form of BC.Using both would help reduce STD risk.

Use protection!: Plan B One-Step is up to 89 % effective when taken within 72 hours (3 days) after unprotected sex. It can reduce chance of pregnancy by up to 95% if used within 24 hours.
