Hi Cadence,
I have successfully used Lullaby opk's and hpt's so I feel I may be able to help you.

It is true and accurate that you are 'supposed' to get a line darker than or the same as the control line on an opk to call it positive. However, a large number of women don't get that. (ME!) A feint line on an opk from lullaby always means I have, am about to or am ovulating. Some women just don't get the dark absolute positive surge. This is for varying reasons. One is the surge can be short and sharp so is easily missed by testing. EG: if you get the LH surge say at 7 am but don't test using an opk until 6pm you may get a feint line. I used many different brands of opk's before realising this. I never have once got a true positive but have fallen pregnant when I have bd'd seeing the second feint line.

As for the feint positive hpt - that is taken as a positive. The rules are different for detecting pregnancy. Any amount of HCG that will turn a HPT to a positive (no matter how feint) means you are pregnant.

Having a feint OPK on the same day as a feint HPT. That is because opk's will turn positive when they come into contact with HCG (pregnancy hormone) so it sounds like you just may have some happy news! I truly hope so...

love Deb
