Quick Answer:

What Does Plan B Do? (Meaning Explained Simply)
Full form
Plan B is short for Plan B One-Step, a type of emergency contraception.
Plain-English explanation
Plan B is a pill you can take after unprotected sex or if birth control didn’t work (like a broken condom). Its main job is to stop or delay ovulation, which means it helps prevent an egg from being released.
If there’s no egg, pregnancy can’t happen.
Plan B does not end an existing pregnancy. It works before pregnancy starts.
Why people use it
People use Plan B as a backup option when something goes wrong or when protection wasn’t used. That’s why it’s often talked about in urgent or emotional online conversations.
Example sentence
“I took plan b the next morning just to be safe.”
Bold summary:
Plan B prevents pregnancy by delaying ovulation when taken after unprotected sex.
