I had the same thing a few weeks ago and my on prescribed me prilosec. Talk to your doctor
I am 32 weeks and 5 days pregnant with a baby girl and I've been like that to these weeks. And I vomit and get sick and it ***** the things that work for me is a cold glass of milk or tums. Both safe and yummy depending on the kind lol. Good luck and hopefully the acid reflux stops.
Here's some advice from the MedHelp website and our I'm Expecting app on heartburn.
You can find this in the app by going to the Pregnancy Diary from the home screen and selecting Acid reflux or Heartburn from the Symptoms menu. Then click the menu bar in the upper left and select Symptoms Manual to see your symptoms. Hope you feel better soon!
