inconsistent bfps?

Danielle
Currently on either 11 or 12 DPO. Got first BFP on 7 DPO on 3 blue dye tests and 1 wondfo. 
Took subsequent tests (digi, Frer, blue dye, and wondfo) from 8 DPO-9DPO, mostly negative, but four bfp with blue dye.
Today: 1 First Response Rapid result very very faint at time limit, clearly pink after 15 hours. 1 wondfo either bfp or evap. 1 blue dye, negative. (images of FRRR and wondfo below)
AF due in 5 days. Have had symptoms since 6DPO. 
I'm so confused, and so sad. Anyone have experience with this much inconsistency and gone on to a viable pregnancy?
Thanks in advance.
