Surprise.. I did this, so you are not alone!
I worked a HUGE company event for a whole week while I was pregnant and didn't know it.. each evening I would have a beer or two.. and low and behold Mr. Monroe was IN me! Oops! Monroe is fine and thriving and doesn't have any instance of something wrong due to drinking when I didn't even know. Trust me.. I felt guilty.. but worrying causes stress, so I tried to let it go.. my motto throughout pregnancy is that whatever was meant to be would be.. and he came out picture perfect! I never drank once I knew I was pregnant.. not even wine.. but I am here to say that if it happened and you didn't know.. please don't stress!
