TMI - Implantation bleeding?

Hi all. My last period started on August 4th. Generally I am a little longer versus shorter on my cycles than the average, so this should still be pretty early for my period. Yesterday I had a little pink when I wiped in the morning, but nothing for the rest of the day. Today I saw a little pink again this morning, but then the rest of the day I have had brown spotting. Nothing crazy, enough to see when I wipe and one little area on my underwear. I have also had cramps over the last few days, with especially today with the small bleeding. Does this sound typical to anyone who has had implantation bleeding before? Tested yesterday and this morning and tests say negative. Thanks for your help 😀
