BFPs with negative OPK possible?

[StephieFranks]

I'm just curious to know if anyone has used OPKs and never had a positive, but got a BFP that same cycle? I would love to hear from anyone who has!

its very easy to miss the surge so entirely possible. I had a darker line than the day before- but not as dark as the control , then the next day it had faded again, I got pregnant that month. Month before got a positive and no pregnancy.

ive seen LOADS of charts (fertility friend) where no surge was detected which resulted in pregnancy, so entirely possible.

I will bear this in mind then ladies - just losing faith in POAS!! Still, only had 1 official AF since coming off cerazette so maybe i should just be patient!!!
