I feel you.. It's been a couple of weeks already were randomly I feel nauseated. A doctor I saw out of routine from my midwife said it could be acid reflux or heartburn now that the baby is bigger and is pushing up against everything. He said for me to take tums. But ask your doctor what they think can help. I still have my anti nausea medication from earlier in my pregnancy and will take it if it's really bad. Good luck mom!!
