Ovulation bleeding?

My husband and I have been trying to get pregnant for 5 months now and I should be ovulating in the next fees days or so. This morning we had a quickie before work and towards the end of my shift I got cramps and generally didn't feel well. I used the restroom and had red mucus in my panties and when I wiped. I'm not sure if this is from intercourse or ovulation. Any ideas?
