Don't get frustrated! I took a test 4 days before AF was due because I was spotting, it was a BFN. Af was due Sunday. Tuesday night rolled around and still no AF; I took a test that night and got a faint line. I took 3 more tests and still got a faint line.
I called my ob/gyn and told the medical assitant my situation, and she told me the reason the line is so faint is because I tested rather early. She said most people wait a week after they are late to test.
Think positive, ok?
I know that is easier said than done, but when you least expect it, is when it happens!
Confused again.....
