Possible Implantation bleeding..

Kendall

So I have been crampy lately.. not bad. Yesterday I really felt different. I've been getting really warm at work and some moodiness. Last night I had some clear cm. and today when I went to the bathroom and wiped there was a big glob and some of it was pink. I am due to start AF between the 6th and the 8th.. I was wondering if I possibly had some implantation bleeding.
