It could be implantation bleeding (try googling that) when the baby implants in the uterus. Or it could be from the extensive exercise, especially if you're not used to it.
You should take a pregnancy test when your period is due, in about another week, maybe week-and-a-half. I'm sorry that you're scared and I wish I could give you better reassurance. But if you are pregnant, then it is a gift from God and you will never imagine life without that dear sweet baby.
