Ok, this may sound strange, but I have had diarrhea for the past 2-3 weeks since after taking the Plan B. I've had some light bleeding for a couple days, then the past two days nothing, and I've had some light clear discharge. I have also just started a work-out regimen, and eat from the "roach truck" that comes to work once a day. Any of these things could be the issue, but I don't think that one would have diarrhea for after 3 weeks of taking the pill, so it could be any number of those things. Also, I am vitamin K deficient, so that may also be another cause. The past couple nights I have been eating my spinach, and taking a vitamin in the morning. I will take a pregnancy test tomorrow, but since I have thyroid, my periods tend to come irregularly, so it could conceivably come this weekend or even next week. Would the clear discharge indicate a period will be coming soon?
