On month #5 of TTC and I am 11/12 DPO. Took a cheap pregnancy test this morning with FMU, thought I saw a VVVFL, so I took a FRER and got what I thought was a positive result (see picture). But when I took a Clearblue digital test, it said, “Not Pregnant.” Are the digital tests less sensitive, or could the FRER be a false positive?

Update: took a digital test 3 days later at 14/15 DPO (day of expected period) and it was positive. Thanks for your advice and support!
