Hi! My period is normally a 31 day cycle. My last cycle was on Sept. 13-16. BD was on the 30th. So I'm assuming I ovulated on the 2nd of October. How many DPO before implantation? If I ovulated on the 2nd today is 9DPO and I think I'm having implantation bleeding. I woke up without anything, had regular urination. Went to lunch, came back to work to use the restroom and it was a very light colored blood. I wiped and it was pinkish brown. Then nothing. Went to the restroom later after, and nothing. Just got home and had more.. Not sure how to attach a picture to show.
