I have taken 4 tests in the last two days. I was not expecting any positive results but the first one was so I took a digital and it was negative. Two cheapies came back with faint lines (I've never had an indent or any kind of false positive on a test or even a faint line) and two digital that doth said not pregnant. Am I just taking the digital too early or did I just happen to get two very messed up cheapies?
