Last night, faint positive.

Today, all negatives.

Waited 12 hours, and have noticed a bit of barely there light pink discharge. Already had spotting of sorts from Friday afternoon to Sunday night. Very light and very short, not like a normal period. I’ve been having all the symptoms for the last week and have just felt off in general. Could this spotting I’m having right now be implantation ?? I tested again just a few minutes ago and it was a BFN. I’m just so confused. Should I wait and test again in a few days, or just give up?
