Week 12+2: Nausea and Gagging Freq Increasing

Hi all, first time mom and currently at week 12+2. I was not having bad nausea or gagging throughout. It was very mild and only happens twice or thrice a day. But since week 11, my gagging frequency increased and when I hit week 12 a few days ago, I have been having very bad gagging and nausea at night till a point I’m losing sleep.. Is this normal or should I schedule for a check?
