Something similar happened with me and it was positive BUT it wasn’t that dark that’s crazy! Definitely see what the FRER looks like!! Keep us updated
Usually once out of time frame, any lines that appear are invalid but I’ve personally never had a negative turn positive. Absolutely try a FRER to double check but also don’t be disheartened if it is negative. Only read it within time frame xx
So I figured it out! Before going to the store I redid what I think happened with water! Sure enough it was “positive”! The wicking side was the side that was wet in the trash can and it caused a backwards dye run! Not pregnant!
Following.. never heard of this!
