Please I need help I’m freaking out

Liberty

Okay. I’m 3 days late on me period. I usually always get my period early by a couple days, and this is the first time it has been the full time and over in a few months.

I have not had unprotected sex. I always use a condom and it has never broke. I think I’ve had it a total of 4 times since my last period.

I do not want to be pregnant, and am currently freaking out and scared. Does a plan B work now even if I haven’t had sex for a few days?
