OPK help, please?

[Starfish83]

Hi folks, am going to start using OPKs to help work out what my cycle is doing (no periods since flrst baby, now 17 months). I’ve dug our my Clearblue OPK, but it’s showing up this static image and won’t flash to show it’s working. Any ideas as don’t want to have to buy another if I don’t have to? Thank you x

Gentle bump in case this gets lost... x

I have had this happen before. I just ejected the test stick and put it back in and it worked. I think sometimes it doesn't work if there isn't enough urine on or something? But I don't think it's faulty, as the error symbol is of a book. I would just try a new stick tomorrow

Thank you, Willow - will try again tomorrow and hope it works! 🤞🏼x
