Okay lol I was going to say. As far as I know there aren't usually symptoms with carbon monoxide poisoning b/c we don't have CO detects in our bodies. That's why it's lethal because it binds to oxygen receptors and doesn't let your body know you aren't getting enough oxygen so you just pass out. If anything you may get a migraine...if you are still concerned it can't hurt to see a doctor but if you haven't experienced migraines or nose bleeds for instance you should be okay (but I'm not a doctor so yea lol)
Actually is carbon monoxide
Carbon dioxide or carbon monoxide...
Carbon dioxide is serious. I would call labor and delivery and ask them.
