Thank you for the info, I do not want to take plan b ever again, I have been reading up on how it really is not good for your body, time for me to start being safer and to really think before I act on things. I actually got my monthly visitor!!! And it's not that irregular (was only a day off) thank you again and be blessed =)
You would need to be ovulating to conceive, so if you have unprotected sex fertilisation and implantation doesn't happen right away. It's until 6-12 days after that you would be pregnant.
You took the pill 10hours after intercourse, so that was well within the time frame of it being as successful as the pill can be - making chances of it failing, slim.
Taking this pill can really mess with your cycles, and is pretty bad for your body. Cramps, random bleeding or spotting and missing or irregular periods can be expected for the first month, or even for the couple after that. To make sure the pill has worked, all you can do is wait at least 2 weeks after intercourse and take a pregnancy test. If it's negative then you'll know its worked.
Correction: I meant to say could I already have a baby growing inside of my uterus?
