Should I be worried??!!

Got my first faint positive 9dpo AM. Started spotting pink when wiping at 13 dpo and have been having spotting for three days when I wipe. Sometimes purple-brown sometimes pink.

My test lines haven’t gotten that much stronger, I don’t have that much progression. It’s not getting weaker but still. Anyone had this??

Update:

Also spotted on 16 dpo. So 4 days almost around the time my regular period would have been. But nothing on 17 dpo today. Been having cramps though.
