I don't know what's going on!

Well today I started getting cramps all of a suddent followed by lower back pains. Strangely I started feeling the need to constantly pee but when I would sit down, nothing came out. I get home and try to use to bathroom again and a little bit came out but as I wiped, I noticed I was spotting with a very light pink color to it. 30 minutes later I go to the bathroom again, and I am spotting a little bit more. I am sexually active, and today is my ovulation date, meaning my period isn't due until the next 14-15 days. Could all these symptoms just be signs of ovulation?
