I start opks on cd7 (purely because I've ovulated on cd10 before). I test once a day until the line gets darker, usually around cd11/12 then I get a super positive on cd14 (well has been cd14 the last few months). I usually use the clear blue ovulation test alongside the cheap opks and I get my Peak in cd14 too xx
I usually only get a positive one day, day 15, almost positive on day 14 and only a very faint line by day 16. Occasionally happens a day or two early so I start testing day 12.
Hope often do you test? At day 12 if the lines getting stronger I test 3 times a day. If you're only doing it once you may be missing it? Xx
I'm only on day 10, test 2 or 3 times a day so still early days I know but opks are completely faint still lol
Don' worry about the fact they're still faint, it can go from practically nothing to strong positive very quickly.
Mine go positive very quickly. One day very faint then the next its super positive. Once I see a shadow I know its close. Keep testing every day x Sent from my Galaxy Nexus using Tapatalk
I get mine anytime from CD17 onwards. My surge is really short, only a couple of hours, so it is really easy to miss it.
