I had unprotected sex on the 1st and 2nd of november using the pull out method 4 times in each day, todays the 4th of November and this morning I blended bit, I don't really know how to tell the difference between whether it was spotting or a light bleeding, but yeah that happened, but I just wanted to know if that would be a implantation bleeding or just something else? I heard that implantation bleeding usually occurs during 2 weeks into it but i am not sure.
