Will Plan B Work During Ovulation?

It's really quite simple: No morning-after pill works during ovulation, as they're designed to delay it. If ovulation is already happening, Plan B (or any other emergency contraceptive pill) will have failed before it's even begun.

Is Plan B effective if you are already ovulating?

Morning-after pills won't work if your body has already started ovulating. This is why timing is so important, especially if you're using Plan B and other levonorgestrel morning-after pills. (ella works closer to the time of ovulation than levonorgestrel morning-after pills like Plan B.)

Can you get pregnant during ovulation after taking Plan B?

The short answer is yes. How effective Plan B is depends not only on how soon after unprotected sex you take it but also where you are in your cycle. For instance, if ovulation has already occurred (within 24 hours), EC may be less effective. This is one case where you can still get pregnant after taking Plan B.
