Using self cleaning oven while pregnant??

Grace
Just wondering if anyone knows how harmful the fumes are from using the oven self cleaning mode? I've read multiple viewpoints and I'm still confused!
I had it on for maybe 5-10 minutes before I turned it off because I wanted to be safe rather than sorry. And even now I'm feeling paranoid that I enhaled noxious fumes during the 10 minutes. Being pregnant has made me very paranoid about life lol. 
I'm curious to know what you guys think and if you've ever used the self cleaning in an oven before while pregnant. 
I just want to get the damn bacon grease out of my oven so I can bake cookies tomorrow! Haha. I may just need to use baking soda and water....
