Is there something wrong with your unborn child if the top of your stomach hurts ever since you started taking Tylenol with codeine?
The pain you are experiencing is probably not a sign that something is wrong with your baby, but it could be a sign that something is wrong with your stomach: codeine is not tolerated well by many people. Having said that, if you had spare pills laying around and started taking them without a doctor's knowledge and direction, that was pretty dumb, considering you're pregnant. Using any medication during pregnancy that contains a narcotic may cause babies to be born with a physical addiction to the narcotic. It's more likely that it is YOU who are constipated as codeine will do that to you.
