2 positive 2 negative

UPDATE 4/27 - see comment below.

Y’all, I’m so confused about this. Does anyone have insight or has this happened to you? If this isn’t the right forum let me know, obviously there’s a line on the FRER but the other two negatives have me questioning it.

AF is due Monday 4/27 and I got peak ovulation on 4/12. I took a clearblue digital on Friday 4/24 (11dpo) and it said Not Pregnant, took a clearblue digital yesterday (4/25 12dpo) and it said Pregnant. Went out and bought the First Response set of 3 (FRER, Digital and then the Rapid Response). FRER showed a faint line. Then FR digital said No-. WHAT gives?! Is it just too early? I’m not going to take the last test until AF doesn’t show, just wondering if anyone has experienced this!
