Implantation cramping?

Hi!

Yesterday marked 10 dpo I felt mild cramping very similar to AF cramps mid day & evening. Prior to this I’ve had loads of CM. Then yesterday I had a streak of like golden brown left on undies but nothing when I wiped. It all stopped late last night.

Could this be implantation? I took a test this morning I’m only 11 dpo no cramps or spotting this morning got BFN. Period is due 6 days on the 28th. Could be too early to have tested.

Would love any advice and stories!
