I took one of those 5 days sooner tests on Monday and it showed a VERY faint 2nd line and I am due to have my period today but I had some brown spotting yesterday. I took on Tuesday 2 more tests and they all have that very faint line. I mean it is so light you can barely see it. I am so confused and want to know if I am or not. I know I should wait till I miss my period but want to know what is going on??
