Duphaston or morning sickness

Anyone taking Duphaston (abt wk6)? I’m currently on Duphaston and feeling very “unwell” especially in the morning. This feeling is like my stomach feels very acidic and I do feel quite nauseous and keep burping until I finally eat something. Not sure if this is due to medicine as it seems to start after I started this Med. If it’s due to this med, anything I can do abt it? (Other than eating more.. 😖)
