When’s the earliest I could test ladiessss

I ovulated this Wednesday 12/13 and we had sex that same morning. My last pregnancy I implanted on 6-7dpo and by the time I was 14 dpo I had a strong positive so I could have probably tested around 9-10 dpo and gotten a faint I’m sure. Should I start testing around that time this time and see or should I wait it out til my period dec 27?!?! Soooo hard ahhhh! When did you ladies start getting a faint line?
