URGENT PLEASE READ THIS!! Wondfo- the brand for cheap internet tests has been giving me faint positives. I was over the moon, told my husband, got all excited. I couldn’t get even a faint line on any other brand (even another cheap internet brand East@Home). I got curious after days of no progress in my lines. I did some reading up on reviews, and someone mentioned their tap water from the sink had a positive line. So I tried it... THERE ARE POSITIVE LINES ON MY TESTS FROM TAP WATER. I tried two and both were there!!!! Ugh!!! Please don’t use this brand. It was heartbreaking to me. 😫😢😞
