Might have eaten bad pepperoni, help!

I might have eaten spoiled pepperoni. I have hyper vigilance, and anxiety. When I ate one slice of pizza today, I noticed the pepperoni had brown spots on it. I couldn't remember if that's normal or not, so I freaked out and threw up. I did not evacuate all of it. It tasted normal. I couldn't smell anything rancid, but I have a terrible sense of smell. What should I do? What risks have I exposed myself and my baby to?! Please help!!!
