I have a bag full of One Step Ovulation Tests. I tried a couple of times, peed all over myself trying to get the sample in the cup, squinted for ages at the lines, confused myself, drove myself crazy, and then gave up.
I have just invested in a ClearBlue Fertility Monitor (£48 on ebay brand new, soooo much cheaper than Boots!) so no longer need the OPKs.
Anyone want them? Free of course.
