just read the article and it is very interesting, when we where trying to get pregnant with our son I was convinced I was pregnant, did the test and nothing happened within the specified time, so I thought thats it for another month, but it turns out that if I had waited for another few mins I would have discoverd two weeks earlier that we where pregant. Think the manufacturers should make it clear on the packaging that it can take longer for a result to be seen, might make for a few happier people.
Very interesting article about pregnancy tests and ovulation kits. Thought I'd share it with all you at gurgle! http://www.cbsnews.com/stories/2003/01/27/earlyshow/health/main538075.shtml
