Doctor :   Hi
User :   hi doc
User :   i have a question for you
Doctor :   sure , please proceed
User :   my girlfriend and i have sexual intercourse 6 days ago
User :   with condom
User :   and to make sure it is protected, i buy th plan b one step 3 hrs later
User :   however what concern me is
Doctor :   ok
User :   will the plan b onestep work?if she had taken one last month?
User :   to be exact it was 25 days
Doctor :   you mean you had intercourse on day 25 of the cycle ?
User :   no doc what i mean is
User :   she had taken plan b one step
User :   25 days before she had one this time
User :   so on april 30 she took one
User :   *march
Doctor :   then in that case , it will not work
Doctor :   let me guide you
User :   and on 25 april she took one more
Doctor :   may i know on which day of her cycle you had an intercourse ?
User :   it past one month already
User :   she had her last period on 14 april
Doctor :   when was the intercourse ? which date ?
User :   the intercourse 25 april
Doctor :   since you have used a condom also, there are very minimal chances that she could be pregnant
Doctor :   ok
User :   however i am being cautious if any of the condom broke
Doctor :   the condom was intact ? any burst or break ?
User :   i dont think so of any burst or break
User :   however i dont know if there is any leak or something
User :   because never experience condom break before
User :   so how often can we use plan b one step?
Doctor :   plan b is not to be taken as usual contraceptive
User :   yes i understand that, but how long is the duration
Doctor :   if your looking for a good contraception with least side effects before marriage, condoms are the best
Doctor :   else go for oral contraceptives which are combination hormone pills
User :   so what about the plan b one step?
Doctor :   but she needs to take them all through the month mostly for 21 days
Doctor :   plan b needs to be taken within 72 hrs of the intercourse
Doctor :   if taken later, its effectiveness decreases
User :   yes
User :   she took it 3 hours after intercourse
Doctor :   in your case i feel as you used a condom ,n9othing to worry
User :   but my question is
User :   if she has taken the plan b one step for last month
User :   and she take another this month
User :   will the plan b still work on her?
User :   thats what i am curious
Doctor :   yes , as she took it after 3 hrs of the intercourse it will work
User :   then why u said earlier it will not work
Doctor :   if you had intercourse on 25 april and she took it 25 april itself, it will be effective
User :   yes yes, but doctor, is it okay to take one plan b step once a month?
User :   because last month she also take plan b one step
Doctor :   no , i would not suggest this method
Doctor :   it is mostly for emergency contraception
User :   so u said that this month the plan b will not work?
Doctor :   it does have its side effects
Doctor :   plan b is meant only for one single exposure
User :   i only had two sexual intercourse
User :   one is last month
User :   and taken plan b last month
User :   second one is this month
User :   and take plan b too
Doctor :   that is if one has sex , then if taken with in next 72 hrs it will prevent pregnancy
User :   so it not going to work this month?or it is still going to work
Doctor :   if a person has sex gaian after this , it willl not protect against pregnancy for the next act
Doctor :   taking plan b again and again will be strenuous for your girl friend
Doctor :   since it is a hormone and she will have to put up with a lot of side effect
User :   yes but on my condition, she had only taken twice doctor, last month and this month
Doctor :   ok
Doctor :   it will work
Doctor :   do not worry
Doctor :   but make sure does not happen again
Doctor :   use condoms always
User :   really?how are u sure it will work doc?
Doctor :   as i told you
Doctor :   if taken with in 72 hrs , it prevents pregnancy
User :   will the plan b one step proceed full effectiveness for the second time she use it?
Doctor :   yes
User :   still the same full effectiveness?
Doctor :   it is effective for every single intercourse
Doctor :   yes
User :   sorry if i am confusing you
Doctor :   that is fine
User :   i am just thinking because my gf ask that last month she already took it
Doctor :   my aim here is to clear your doubts
Doctor :   hope you are not confused
User :   and this month the second time she took plan b one step pill
User :   she ask me that if it going to work this time
User :   that it is
User :   please answer
Doctor :   yes
Doctor :   it will work
Doctor :   if you have doubts
Doctor :   do a urine pregnancy test at home
Doctor :   to confirm the pregnancy
Doctor :   i see nochances of it
User :   you sure 100 percent it will work?
User :   let say the condom broke?
Doctor :   i would say that 0.3% documented failure rate
User :   i am wrong?
Doctor :   No, you are absolutely right, but i do suggest to get a urine pregnancy test done in home to confirm it.
User :   but u said bleeding still are no sign of prgenant
Doctor :   As explained before, it has failure rate of 0.3%. Just you make sure it would be better to get it done.
