TTC using frozen specimen

Hi everyone, I’m new here! My wife and I are TTC for the first time. We used frozen sperm from a donor bank and inseminated using syringe/softcup/preseed.

I have been getting progressively darker lines on Walmart cheapie but negative frer still. Anyone have thoughts or experience?

I’ll post this morning’s test, the line showed up immediately.

I’m 12 dpo, thought I might have felt implantation the evening of 9 dpo.

Any help is much appreciated! This is hard!!!
