You can't beat the price on these pregnancy tests - that are under a dollar at Walmart, so if you are TTC-ing, grab a whole bunch of these. They are so much cheaper than the other tests. I bought a few of these to test after I had tested positive... I was nervous that it could have been a false positive. Sure enough, these tested positive too. The only hard part about these is that you have pee in a cup, and then use the included dropper to add urine to the window. I was lazy, so I peed on the test directly! Your hands aren't gonna stay clean! But it works.
