Natalie,

I found an address for you. I am not sure of the cost, but this lens
has a life time warrenty. I talked to my sis-in-law about the lens
again and she said that she didn't really trust it after all. It did
not always coincide with her mucus and temp. signs. I guess it
should just be used as a secondary tool to be on the safe side. But,
we are by no means experts on this. Hopefully, the company can give
you more info.

The address is:
OVU-TECH
PO Box 2708
Ocala, FL 34478

By the way, what does "dh" stand for? I have seen it alot, and just
can't figure it out. :) I think your talking about your hubby, but I
don't know what the "d" is.

Hope all is well.

Pam
