I thought my period was late, so I took a test. When I wiped after the test I got some brownish-reddish mucus on the tp and I thought "Ok, I'm out". I set the test on the counter and left the bathroom. When I came back to check I saw a very, very faint line. Now, it had been longer than 2 minutes so it is possible that it was a false positive/evaporation line. I have not actually started spotting, and I checked tp again and didn't see anything. But about 30 minutes ago I started having cramps. ARGH. So now I just wait. I may test in the morning, but I think I will wait a few days and see if AF starts.
