Is this implantation bleeding?

So I’ve had some pinkish discharge since yesterday. My period isn’t due until 7 days from today. This morning I noticed more pink discharge and then a bit more when I got to work. It’s not a lot but enough for me to need a panty liner. My last period started on the 5th and I think it was two days earlier than it should’ve been. I also took ovulation tests all last week and never got a positive so I’m wondering if I ovulated sooner maybe the week my period ended which was the 10th. I’m not having any of the normal signs and symptoms I typically get around my period or what I experience when I’m ovulating. The only other thing aside from the spotting/discharge that’s different is the fact that I was getting a lot more irritated over things that typically wouldn’t bother me.
