Plan B or implantation bleeding?

So I'm a bit nervous. Two weeks ago I had my first PP period, 3 months after giving birth. One week later on 11/29 the condom fell off during sex and on the 30th I took Plan B. Now 5 days later, I'm having reddish brown spotting. Not even enough to mark a pad. Is this normal after plan B or should I be worried that it failed and its implantation bleeding? I've never had implantation bleeding before, nor any side effects of Plan B before.
When should I test to be sure?

Nobody?
Darn. I looked it up on yahoo too and lots of people had the same problem, but nobody posted again to say if they were pregnant or not.

are you due for your period?
plan b never made me bleed. I have taken it 3 times.

Plan B can cause changes in your cycle or spotting like that. I believe it even says all that in the little booklet that comes in the box with it. I never had issues like that when I took it though.

I don't think I should be due for a period for another two weeks. But I just had my son and one PP period so far. So my 30 day cycle could have changed.

Yeah I've taken it 3 times in the past few years and have never had bleeding from it. Now this time I'm getting blood almost a week after.
Ugghh, I hope its just the pill.

I'd just give it about 2 weeks from the day you had sex and take a test. If the first one is negative and you still haven't got your period, then test again in a few days. It is possible for plan B to throw things off a little though.

Ok, thanks. I really hope its just the pill. Its to soon to be pregnant again lol.

Plan B treated me HORRIBLY. I vomited, had severe abdominal pain, and did bleed pretty much like you said you were. I even went to get checked out because I wanted to be sure I wasn't mc'ing and took it not knowing I was pregnant. I wasn't; I just had a horrible and painful reaction to the med.
