Taking my BBT and doing OPKs has been getting stressful for me so I decided to take the plunge and order an AVA bracelet! I'm so excited for it to come. Yes, it's pricey, but if it helps me get my BFP it will definitely be worth it. That said, if anyone is looking to buy one here is a $20 off code: http://avawomen.ref-r.com/c/i/10619/9643629 If you type that into Google (or whatever you use) it will take you to the AVA webpage. At the very top there will be a small blue/green banner that says something like "Welcome friend, use this code for $20 off. . ." and it will give you a code that you can plug in at checkout! Standard 3 day shipping is only around $3 (at least it was for me). Good luck all!
