Hey ladies! I took apart my clearblue advance (Honestly it felt good ripping it apart because I was so pissed of my BFN) . I didn't realize that the battery inside are the replacement batteries for my key fob. I was crying and then laughing because I thought of the saying when life gives you lemons, make lemonade or something close to that. I guess when life gives you NBF you use that battery for your key fob. 😂 #babydust to all and to all a good night!❤
