Question 1

does plan b work 4 days later?

Accepted Answer

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!

Question 2

does plan b work after ovukation?

Accepted Answer

Yes: Plan b can be used after ovulation. It can be used at any time during your menstrual cycle.

Question 3

how does plan b work, and how long does the medication stay in your body?

Accepted Answer

Preventing ovulation: The medication works by inhibitting ovulation. Thus, no egg, no pregnancy! 
the half-life of the medication varies greatly ranging from 11 to 45 hours and so it is difficult to say for sure. Based on this, it stays in the body for about 2.5 days to just over 1 wk. 
If you still have question, post it here or consult your doc. Good luck.

Question 4

does plan b work if your overweight ?

Accepted Answer

Yes: Plan b onestep can still be used if you are overweight.

Question 5

does plan b work 1 day before ovulation?

Accepted Answer

: If you take it within the time listed in the products instructions it will work as well as it can whether you are ovulating or not.

Question 6

does plan b work 5 days before ovulation ?

Accepted Answer

Sure: Plan B "works" fine before, during, or after ovulation. That just means that if a woman needs emergency contraception after sex (which she should only need about once or twice in her entire lifetime, because she uses another reliable birth control method at all other times when babies are not desired), she need not worry about what time of month it is. Plan B is of course not 100% effective.

Question 7

how does plan b work when you're ovulating?

Accepted Answer

Plan B: Given the uncertainty in timing of ovulation, emergency contraception is offered, when indicated, without regard to day of the menstrual cycle.

Direct laboratory evidence overwhelmingly supports the hypothesis that oral emergency contraceptives work primarily by delaying ovulation.

Treatment is ineffective once implantation has occurred.

Question 8

does plan b work as well on overweight women?

Accepted Answer

Maybe not: The Plan B pill may not be as effective in overweight women.

Question 9

does plan b work if you have already ovulated?

Accepted Answer

Plan B can be used: at any time during a woman's menstrual cycle. 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. It continues to reduce the risk of pregnancy up to 120 hours (5 days) after unprotected sex, but is less effective as time passes.

Question 10

does plan b work if taken the day ovulation starts?

Accepted Answer

Yes: It works if you take it within 72 hrs of unprotected sex irrespective of the cycle date.
