I need everyone’s help and opinions please! Pregnancy test efficacy question!🧐🧐🧐

So I bought these Wondfo Early Result strips from Amazon and they seem to be giving off and on faint lines and also just found out they weren’t shipped from Wondfo, but a China based company?

Has anyone else had this issue with this particular brand??

This is the Wondfo compared to my AccuMed result I got (for the third time)

^Wondfo Early Results unaltered

^Wondfo Early Results (inverted)

^AccuMed

^AccuMed unaltered (veryyyy faint colored line)

Faint line on AccuMed (like before)

^AccuMed at bottom**

^3rd vvvfl AccuMed
