13 days dpo- bfn but no signs of af

Lottie

I posted tests at 10 days dpo with a vvvfl but I think it may have still been the trigger shot from my iui since frers are sensitive. Minor cramping and spotting 11-12 days dpo. Usually by then I am doubled over with af cramps and have consistent spotting. This was different. This morning I took an easy@home test (notnas sensitive as frer) and got a bfn but still no signs of af. Do I still have a chance?
