Pdg tests?

I have some fertility issues and my O (ovulation) day is never really consistent. I track my period, take bbt and take ov tests. My doctor suggested me to take pdg tests to keep track, I couldn't find one for a long time, then I came across Easy@home pdg test on Amazon when I was placing my opk order from them. It's very helpful. Especially with their new Premom app, you can upload all your tests to their gallery to keep visual progression records of your tests. I would say they are very professional and knows what we need.
