I tested 10dpo and got a faint positive...Good luck!
10 days with an accurate test and FMU. 14 days with a standard test.
It just depends on how soon it was implanted and how your body is producing hcg. I tested 10 dpo and I got a positive.
You can test up to 14dpo with a first response early response, but it's more accurate later on around when your period is due.
