Implantation spotting? Or period...

Jessica
I triggered on 11/20, ovulated on 11/22. I started spotting on 12/5, so I took a pregnancy test to see if it could be implantation spotting- it was negative. I spotted on 12/6 as well, not no spotting today (12/7) 
I sgould be starting my period this week, should I take another pregnancy test this week because I only spotted two days and haven't had a full blown AF
I am hoping that's what this is and it's a BFP!! 
Thanks ladies
