If you took the morning after pill 12 hours after intercourse then that's fine, it should cover you as you can take it up to 72 hours after intercourse, but take it as soon as you can as the later you take it, the less reliable it is, it shouldn't matter when you had your last period just so long as this was your only time from when you we're last on that you had unprotected sex, and that you weren't sick after taking the morning after pill, everything should be fine
The morning after pill is best up to 24 hours after sex, not worth taking at all more than 72 hours after sex. What it does is make sure that even if an egg is fertilized, it doesn't implant in your uterus.
A little easier on your body: preventative stuff, like birth control - get the lowest dose that actually has an effect on your body - and condoms. Used together, they're *almost* as effective as not having sex.
Do a little research on the different methods available to prevent pregnancy - online or with an actual physician/birth control clinic, it'll save you a lot of stress in the long run.
You have 72 hours to start the morning after pill. It is not 100% no matter when you take it. You should go back and get out on birth control though because it is not good for your body to use the day after pill. And the "Pull-out" Method don't work. Logan Andrew is Living proof of that one... he is 3 months. You just need to take it and see... be very careful from now on, and if it happens, then GOD had it planned for you and nobody could change it....
Best Luck,
