I think Plan B posts that there is a 1 in 8 chance of it not working. It's not meant to be used as birth control, it's meant to be used as emergency contraception. When you say "condoms aren't on the table," do you mean this has already happened and you had no condoms? If this hasn't happened yet, condoms are more reliable than Plan B, and a lot more healthy for you.
It's already happened, but I had him finish in me a few times, should the Plan B cover the pregnancy factor or should I be worried?
If you took it within the right time frame, then it will work as well as it can. Which means, a 7 out of 8 chance. Were you in the middle of your cycle at the time? It is possible you were not at the right time to ovulate.
My period just ended a few days ago, what worries me is if the pill can prevent the pregnancy on it's own and if the volume of semen can change the effectiveness of it. It seems silly but I want to be sure we wont hear little feet running around soon!
Okay, that makes sense. Thank you very very much Annie! :)
