.. did Plan B work from when i took it 4 days ago or should I be concerned? And take it again asap?
It would be pointless taking Plan B again, as even if the first dose didn't work, Plan B is only possibly effective up to 72 hours/3 days later.
You'd need Ulipristal Acetate or to have an IUD/coil fitted by a doctor, within 5 days of the unprotected sex.
It's impossible to know this soon if Plan B worked for you. When did your last period start, & are they always regular? I can probably give you an idea based on that info.
