For a few days I have noticed some small cramping and thought nothing of it really. Then today I noticed some light spotting that was a pinkish color when I wiped. My period is not due for about 5 or 6 days and I had sex during my ovulation, though he pulled out. We have been using the pull out method for all of the 3 years we've been together and have never gotten pregnant. Though we have had scares. I looked up an implantation chart and it says this is around the time I would. The spotting turned from the light pink color to a list brown color.not sure if it is implantaion, breakthrough bleeding or my period early. But I am always very regular
