One year pregnancy guarantee?!

I went crazy one day and purchased an Ava tracker to help me to understand my cycles better. Does anyone have this and had time to test it for a while? Has it worked? Is anyone thinking of buying one? I bought the upgraded package because it includes a one year money back guarantee of pregnancy. If I don’t get pregnant I get the money back and if I do, then it was worth it... right? Has anyone had actual experience with it and gotten pregnant?

Also, anyone thinking of purchasing it, here’s a code for $20 off
