Question...?

So, this is going to be a bit TMI, but I am really confused. I'm in my fertile week. Hubby and I are trying to bd every night, but were mixing it up a little. So tonight we were fooling around (not sex yet, just foreplay) he was "doing things" to me and when he pulled his fingers out, there was blood. Not a whole lot, but enough to make me worry. I'm not sure if I should be concerned about this or not. It's just like really really really light spotting, but it's not stopping. It's a light pink color. Anyone ever had this happen before? I'm super confused!
