Is this a positive OPK? (I don’t have the thing for the 😊)

Roxy

Would you say this is positive or almost positive? I forgot the 😊 insert thing. I usually get a positive on CD16 and it’s CD13 (first day testing and wasn’t expecting the line to be so dark) I’m on soy isoflavones so I think it moved up my ovulation but not sure. Help!
