6 dpo and a little confused!

So I don't really know what's going on, but I'm having some bleeding today. TMI - it's bright red and maybe a little watery. My chart still looks really good - my temp is still high. It's just kind of strange, and it came as a total shock.

Of course I'm hoping that it could be implantation bleeding; that's one possible explanation, anyway. I don't know what else it could be, but I really hope that I'm not going to have another cycle with a ridiculously short luteal phase. I looked at my chart for the cycle where my LP was only 8 days (5 days shorter than usual) and it doesn't look anything like my current cycle, so hopefully my LP isn't going to be an issue this time.

I'm keeping my fingers crossed that the bleeding/spotting could be a good sign - that's about all I can do right now anyway!
