Implantation Spotting 7dpo

I have had 4 babies before, two of them I had implantation spotting. When I did it was when I was peeing and I wiped it was a faint color or super light, only that one time when I wiped and wouldnt happen again. Also I had egg white cervical mucus when i would wipe after peeing a This is what happened to me at 7dpo this cycle. I wiped and that was it, no more, havent spotted and currently 9dpo and getting a negative pregnancy test as of this morning, however I know that it’s still early, as I didn’t get faint positives until 10-12dpo with my previous pregnancies. I read online it can take anywheres from 3 days on after implantation to get a faint positive on a frer test. Planning on retesting on monday (I’ll be 12dpo) and 2 days before missed period. I hope this all makes sence.
