allhailtheaubergine - this is my first month of using OPKs. I bought a pack of the mega cheapie ones (about a fiver for 30 plus 10 pregnancy tests) from eBay. Weed on two a day (one at about 11am, one between 2 and 4pm) from CD11 without so much as a whisper of a line and then got what I thought was a positive on day 18, but now on CD 21 with no temperature rise so am wondering if it was a positive after all (I'm not really selling them, am ?). You don't just have to get two lines, like with a pg test - the test line has to be as dark as the control line. On my "positive", half the test line was as dark as the control line (although half wasn't) so I decided it was positive but this may have been wrong. My experience so far is that, while they give you something to do, and make you feel pro-active, they are not exactly the Insta-Preg solution I was seeking. However, no doubt someone else will be along in a moment to tell you how they conceived their triplets using OPKs despite having no uterus and not having had sex at all, so don't necessarily listen to me.
If you use them, perhaps you could wee on them in soft-focus while scattering rose petals on the bathroom floor?
Still, despite the fact that I appear not to have ovulated, I am of course still pregnant (as is everyone on this thread
).
