Hi! AF was due on the 26th or 27th of Feb. Tested on 28th and BFN. Just got back into town, used this digi. It stayed on the clock symbol so I took it apart (naughty, I know, but I read several posts from other ladies saying to do this). It flashed all the symbols (yes, no, ?) And ended up this: yes+ with the clock symbol. I've Googled ans read other ladies stories of when this happened and half were actually pregnant and about half werent. Wondering if anyone experienced this before?? Thank you!!
