Ok, so I am not TTC this month, but I am taking OPKs partly just to pee on something for fun, and partly just to make sure my temps match my LH surge and when I think I ovulate. This will give me more info for when I do get back to TTC. Well, a few days ago, I had a line on the very edge of my OPK, and thought that one little sliver was darker than the light part of the control line. I thought maybe it was positive – especially as the following days my OPK never got any darker, until today. Well, what a difference a day makes! The line went from super light to glaring positive in under 24 hours. Hubby and I are being extra careful, and not ‘doing the deed’ until next week – but it was cool to see the progression and to confirm that the thin line on my OPK the other day was not a positive. I’ll post a picture to show you what I mean.
