Brownish spotting 2 weeks after taking plan b?

Hi lovely_j

Some information for you. Plan B or "morning after pills" work best when taken within 72 hours after having sex - preferably immediately after sex.

You should have a normal period within the next month after taking emergency contraceptive pills (also called "morning after pills" or "day after pills"). Sometimes, emergency contraception can change the length of your monthly menstrual cycle, making your next period come as much as a week earlier or a week later than usual. Some women also find that the hormones in the pills can cause unexpected bleeding, but this is not a common or serious side effect. If your next period is late, you might consider getting a pregnancy test. 

P lan B is less effective in women weighing 165 lbs (75 kg) or more and not effective in women weighing more than 176 lbs (80 kg). If your weight is 165 lbs (75 kg) or more, ask your healthcare professional for advice on alternative methods of emergency contraception.

Hope this helps
