On 2/3/03 we bought the Clear Plan Fertility Monitor on eBay for $199. (Used once by another couple -- they got pregnant.)

It was a brand that was highly regarded by the press, as well as fellow couples who had used it to track ovulation and fertility.

On 5/25/03 we sold the Clear Plan Fertility Monitor on eBay for $199 -- after we still had not become pregnant. (Luckily we got our money back!)
