Don't use walgreens tests.
I've spent over 80$ on Their name brand tests. They are junk. They give false positives and have a line on them even before you pee on it. This was mine,
Now I'm not saying you cant get a positive. But sure as shit my period came when it was supposed to. So before you use these, don't waste your money. And if you choose to do so, look at the test before you pee on it. You'll see what I'm talking about. It's heartbreaking when you see a line but its not a pregnancy, its a lie.
