OMG! Trying not to get hopes up!! Implantation cramps?

Okay, so I am thinking that I ovulated on or around July 19th. We BD'd on July 11th, July 18th, July 20th, and July 21st. Anyways, on July 26th and yesterday (July 27th), I've been having some mild period-like cramping. Just a minute ago, I went to use the bathroom. When I wiped, there was a speck of blood on the tissue (sorry TMI), but when I wiped again, nothing was there. I'm currently 9 DPO. My next period isn't due until August 7th (but I tend to ovulate at random times during the month) So, what do you guys think? Could the small speck of blood and the cramping be implantation cramps? Could this be my month? Let me know what you think, thanks!! ♥
