Implantation bleeding?

Alanna
My husband and I have been TTC our second child. It's been 14 dpo and my aunt flow is now a day late with I usually start a day or two before she is suppose to arrive. Today I experienced very light pink blood? Sometimes it's there when I wipe sometimes it isn't. I was wondering if anyone thinks it could be implantation bleeding? I did take a test yesterday and it was negative
