Off Nuvaring! Implantation bleeding?

Okay guys youll have to pay close attention and read carefully what im about to explain.

Ive been on nuvaring almost 3 months. May 21st i took out the ring to start my period. The next day, 22nd it started and ended the 27th. So lasted 6 days.

I put a new ring in June 2nd because i forgot to put it in after my period was over. I took it out June 9th because it was getting horribly uncomfertable during sex. Days have passed. June 15th I had a bright red not a lot just medium light, the next 3 days just had brown spotting with a little white creamy discharge. All this only lasted 4 short days VERY lightly spotting when i wipe. Is that implantation? It just ended the 18th of june. Which was yesterday. Its 12:30 right now so its the 19th today. When do i test if it was implantation?
