Don’t test again until AF due date or after its late. Implantation can be as late as 12DPO. HCG doesn’t start building until after implantation. I’m 8wks and had very light implantation spotting on DPO 11-12. If I had tested any time before 13DPO I would have had a BFN!! Good luck!
I am 9 dpo as week and have been ttc for 2 1/2 years. I’m testing every day and getting the same result as you. Don’t loose hope! Try again in a few days. Baby dust to you! ✨👶🏼
