I just bought the clear blue digital test. I used a cheap Wal-Mart test 2 days ago and it came back negative and had no control line which means it's faulty. I still have no period. When should I take the test? I'm a little impatient. I kind of want to take it right now at 10pm. But should I just wait until morning when I get up for my first pee??? *****EDIT ***** My period was due 2 days ago.
