Question 2

do plan b really work ?

Accepted Answer

Yes: Plan b is there, of course, because the better method plan a is not present. 
Plan b does work. The sooner it's taken the better it works. The effectiveness gradually decreases over the next 5 days
a newer emergency contraception called Ella (ulipristal acetate) has more even effectiveness over the next 5 days.

Question 3

how do plan b pills work?

Accepted Answer

Hi dose BCPs: They are basically high dose BCPs which make the uterine wall a hostile environment for a potentially newly fertilized egg and so it cannot implant itself and grow and so it just flows out with ensuing menses.

Question 4

what if plan b does not work?

Accepted Answer

Options: Then you have to think about the possibility of being pregnant and figure out what options are available to you.

Question 5

does plan b work 4 days later?

Yes, but diminishing: Studies have shown that women can still benefit from using Plan B as late as 4 days after unprotected sex.  It's better than not using is you're worried about pregnancy.  The sooner you take Plan B after unprotected intercourse, the better, but taking it is better than not!  hope that helps!

Plan B: If you take it within 72 hours after you've had unprotected sex, Plan B One-Step can reduce the risk of pregnancy by up to 89%. If you take Plan B One-Step within 24 hours, it is about 95% effective. But you should know that Plan B One-Step is not as effective as regular contraception.

my weight is 180 would plan b still work ?

I would assume so.: Don't know your BMI. But I would trust the medication to work. Plan B may require a higher dose with obese women. REF:  See:   http://www.npr.org/sections/health-shots/2013/11/26/247226093/emergency-contraceptive-pill-might-be-ineffective-for-obese
