Implantation Bleeding??

Carms💜 • 31💜 11 years married💜Boy Mom💜8,7 & 1 year old💜
Sooo i ovulated on 3/15-3/16 ... Glow says AF is coming on Monday.. I've had no cramps or anything.. I went to Pee like an hour and a half ago and it was pink on the TP and now I just went and it was normal no pink.. 
Doesn't implantation happen a lot sooner than 2 weeks after? 
Someone help
