False Alarm?

So, I am confused again. Remeber earlier when I said AF was here? This may be too much information, but I have to write it somewhere. I came home from the gym earlier about 1:00 p.m. and went to the restroom, there was a little bit of brown discharge and a little more when I wiped. I assumed that meant AF was here, so I put in a tampon and forgot about it. Well, I never have "spotting" when AF comes. It just starts, and it's not usually brown it's bright red, so I was thinking about that and the fact that I'm not really crampy like I usually am the day I start. So...I went up and checked my tampon. There was a little on it, but all brown, no red and now when I wipe...nothing. So I put on a pantyliner and will see what develops. I also took my temp, which means nothing this time of day, but it was 98.7 which seems high to me. I'm not really sure what I'm saying, but technically a new cycle doesn't start until the first day of regular flow, spotting doesn't count. Like I said, I've never spotted before AF before, so I'm not really sure what's going on. I guess I'll keep watch for the real stuff and see what my temps do tomorrow? It seems really late for any implantation signs like temp dip or spotting. Hmmm...
