Period or implantation ?

Anna • Wife, college student

I took a test 7 days before my period and is was positive with a faint line, 5 days before my period I got a negative.

I read that implantation bleeding happens around your 21-26 days in your cycle for 1 to 3 days.

Today is the 25 day in my cycle and I have brown- jelly/water like spotting. Very very small amount, not enough for a tampon or even really a pad. It’s more brown than the picture seems.

Do you think this is implantation bleeding, or just my period? I want other opinions, I get in my head and overthink a lot lol.
