I just have to warn everyone out there ttc! DO NOT buy walgreens brand pregnancy tests. I got THREE false positives. Not just the "might be there" lines, faint but definately there pink lines. I got my hopes up and was even about to call my doctor when I took a few other brands that were all negative. So a few days later, lots of other tests, and finally a period, determined I was indeed not pregnant. After trying for a while it was such a disappointment to see those 2 lines and have them not be real. Reading other reviews on these tests I found out this has happened to many other people, please warn anyone thinking of picking some up!
