So thinking of trying opks for next cycle & have a couple of Qs for those who already use them. - Roughly how many should i buy? Looking at what presumably are the cheap test strip ones on amazon, and they vary between packs of 20 / 30 / 50. How many do you get through each cycle? - i drink a lot of water in the day but seen on here that doesn't bode well for opks. Probably wouldn't take them to work, so would only use them first thing in the morning and maybe couple of times in evening. Evening pee being more diluted obviously! Is this enough to get a good use out of them/see a result? I know everyone is different but your experiences on how useful/effective and when you think it works best would be so useful. Thanks for your help!
