FWIW - Wondfo's repeatedly gave me evaps at before the ten minute mark the last two cycles. One ended up in nothing, the other was a chemical pregnancy.
This. Last ttc cycle I got a line with color in the time frame but the FRER was stark white. I don't trust Wondfo's anymore.
With that being said I do see the lines and they look like they have color, retest in the AM like the others have suggested. Check it with a FRER or digi though. Best of luck!!!!
