I only can eat small portions of food at a time 😑

Today I felt so much better than the other days dealing with MS. So today I had a taste for spaghetti and I made it. I could only eat a little maybe a few fork fulls.. And I was full.. My husband laughed and said give me yours lol.. Can anyone else only eat small portions. I want to eat so much but get full so fast lol.. Help 😒 Did I mention I'm 8 weeks and 1 days along. Is this normal?
