ive jsut started using opks this cycle. the darkest line i got was w lullaby conceptions but it was not as dark as the control line. i've also used Discover and Ovuplan, both hardly can be seen. I did this when I had EWCM. i dont think i had much last mth, but more this time.
The 2pm is hard, im sneaking around to the loo with my mobile phone as a timer and opks in my pocket. made sure i wore pants w deep pockets!!

For some reason, ive been dry, so have been using pre-seed. i did some research from their website and they claim to be all sperm friendly. so i hope this is harming my chances of conceiving. i found them more 'natural' then the other lubricants.
