TMI!!! could really use some advice please

Geri🇮🇪 • GeriHB Roscommon Ireland 🇮🇪 ..... Mommy to a beautiful little girl and a handsome baby boy 💙
So I posted a few weeks ago with a very swollen stomach and it hasn't gone down since... I am normally flat stomach and size uk 6/8, not constipated, don't feel bloated, had barely any bleeding (AF was 10 days early), took pregnancy tests (BFN) and have a doctors app tomorrow! Genuinely scared something is wrong, I do suffer with my stomach but it is never ever this swollen to the point where I feel nauseous! Pictures below were taken just a few minutes ago!! If anyone has any ideas could you please share... I know I have doctors tomorrow evening but it's only 10:30pm here!
