Implantation bleeding?

My period isn’t due for another 14 days but today I noticed on the toilet paper it was very pale pink, I wiped again and the same! Nothing else since this afternoon though. We have been ttc for over 12 months and I have been tracking ovulation on glow and according to that I am in my peak now, we usually do it daily so is it possible these ovulation dates are wrong and I ovulated earlier and that’s why no success as yet? I have never had I/bleeding with my 2 previous kids and I can’t find an answer anywhere :( Can you have implantation bleeding 14 days before a period or is it too early? Thank you :)
