Help please. So confused 😫😫

So I’m currently 10dpo, 4 days away from my period. I’ve taken a test 9dpo then this morning and both negative.& then I started to cramp and bleed this early afternoon. But the bleeding is really light and it’s brown/super super light red like pink with some stringy discharge. I thought it was my period but a few friends are saying 10dpo is a prime implant time and it could be that and that’s why tests are negative?!

How was your implant bleeding/cramps??? And how many dpo????? This is a rainbow baby we’re trying for! ❤️❤️❤️
