Have anyone used the OvaCue fertility monitor? I've always had kind of long cycles with a possible luteal phase defect & I am considering purchasing one of these to assist with TTC but it's reasonably expensive so was just after some feedback. For those who haven't heard of it it uses your saliva to track your levels of estrogen giving you a more accurate picture of your fertile window & there is a vaginal wand that also tracks your levels of progesterone to let you know when you have actually ovulated. So pretty fancy!

Thanks!
