Test question

Shieanne
Hey ladies I posted a couple days ago about a pregnancy test questions I have another I decided to take another this morning since results came really fast last time this time it turned instantly positive then it went negative then it went positive to negative back to positive so now I'm super confused I never in my life heard of a test switch that much I hear them go positive to negative or other way around so any suggestions???? Also just went bathroom again light spotting?
