When to test post implantation bleeding?

Erin

How soon after suspected implantation bleeding would be best to test? I’m CD 23 and 9 DPO. I’m trying not to get my hopes up after two chemicals and a miscarriage over the last 10 months TTC baby #2.

I had planned to test tomorrow with a FRER but I’m wondering if I should wait until Monday for most accurate results?
