3 positive days with OPK?

Today is CD 13 and I just got my 3rd positive reading from my OPK. I'm using it as back up to the CBFM because last 2 cycles I surged but didn't ovulate then surged again. So far this is what this cycle looks like:

CD 8 CBFM low. OPK negative. BD
CD 9 CBFM high OPK negative
CD 10 CBFM high. OPK negative
CD 11 CBFM peak OPK positive. BD
CD 12 CBFM peak. OPK positive. EWCM
CD 13 CBFM high. OPK positive BD

Until I used the OPK this evening, I assumed I probably ovulated on CD 12. Does the continued positive OPK mean I still haven't ovulated? Should we keep BD? Why didn't the CBFM catch the continued surge and give me another peak? I'm using Target OPK with the 2 lines. Last cycle my peak days on the CBFM and positive OPK were a week apart.

Re: 3 positive days with OPK?

from what I've heard the OPK's can sometimes be unreliable (at least the digital kind like I use). I had my smiley on 12/18 and still no AF and my LP should definitely not be this long. Not sure why you'd have a positive for 3 days but as long as you're then you have your bases covered....good luck!!!

Hmm, i guess we'll keep BD. its just so difficult to DTD so many times on command. I also feel like the CBFM is so expensive shouldnt it be more sensitive than the OPKs? It seems like after it detects the first peak it goes into automatic mode and doesnt really analyze the sticks any more. Today, CD 14 i got a Low reading.

Ive found cbefm to be more reliable than opks.... then again im still not pregnant lol
