How often do you test? This is my first month really using them so I bought internet cheapies and I'm using them like crazy till I learn. I got only 1 line for about 7 days, I mean there was absolutely nothing on the other side. Then I got a really faint line... the next morning I got another faint line and decided to test again in the afternoon and it come out positive!

So I tested again in the evening, still positive. I tested today and it still looked positive BUT compared to the 3 from yesterday, it's a touch lighter.
So, maybe when you get a faint line try more than one test a day? I find it so tough no knowing what's going on, and if the right things are going on... so this month I was determined to find out! lol
