I am currently 15dpo. On July 27th I took a test & I got a VFL, I took 2 more with the same outcome. AF was due August 1st, but July 29th I experienced light spotting.. I thought maybe it was implantation bleeding. But, July 30th it became heavy. Sadly, I assumed it was a chemical pregnancy. Today, however, the bleeding has become very light & as of right now, I am not bleeding at all. I usually do a full 7 day cycle.
