TTC? Find out when you're most fertile with our ovulation calculator.
Just realised all my clearblue ovulation sticks went out of date last month, or rather i assume that is what the stamped date means! Is that right, do they go out of date?
Yeah they do have an expiry date, but I doubt they stop working the second the calendar flips into February. Probably just become less sensitive the older they are, but I'm sure they'll be reliable enough for another month or so.
