i had never heard of it, so i looked it up: https://www.firstresponse.com/fertilitytest.asp
and i looked up some reviews:

https://infertility.about.com/b/200...ew-at-home-first-response-fsh-levels-test.htm

According to these reviews, I would say, Don't buy it. Just go to your doctor. Even on the walmsrt website, the customer reviews are bad. Pretty much people are saying that this tests an age related infertility factor, (only one of the possible factors of infertility, so it can give you false hope) and it may not be accurate because of the sensitivity of the test.
