Implantation

Ebbi • Hubby and I have been together almost 10 years. :) 06.30.08 and we`re trying for our first baby! 😁
So I had a very light pink bleeding & slight cramping 5 days after my ovulating day, then it stopped and didn't happen anymore. When should I take the Ptest ? I don't wanna get my hopes up cause this light pink has never happen to me before. and I don't feel any symptoms of being pregnant. What should I do?
