The : The odds of you getting pregnant under these circumstances are very low. The fact that you just finished your period means that you will likely not ovulate for another ten days or so (however this is variable), the Plan B is also very effective, however the effectiveness goes down the longer you wait to take it after the act; and lastly some semen that may be released prior to ejaculation is just that a lot less than if ejaculation occurred. Like i stated previously the odds are pretty low. Best of luck to you.

Plan B: Plan B One-Step can reduce your risk of pregnancy by up to 95% if used within 24 hours of sex. If taken within 72 hours it can reduce risk of pregnancy by up to 89%. Use protection everytime you are sexually active - even if there is only partial penetration.
