Trouble swallowing

Hi there! I'm 12 weeks pregnant and lately I've been having trouble swallowing. It usually starts around noon and lasts until I wake up the next day. It's everytime I eat where it feels like the food is stuck in my throat and I'm constantly coughing trying to get it to come back up so I feel better. I drink so much water trying to push it down but no success. I never had acid reflux before but that's what I'm being told it might be. Has anyone else had this feeling? If so, what did you do to help it?
