False Positive

I got a faint line on a rapid result first response pregnancy and just the 1 no others even showed a hint and I did some research afterwards it says first response has been notorious for this since January so beware because this is the second time I've had false positives the first time was 2 tests for the off brand of first response I got refunded but it still stings to get so excited and find out it was never real sorry for the rant I just want other people ttc to be aware and possibly save others from disappointment 😔
