Sudden no appetite in week 24

Hi mummies, 2 days ago, I have experience the worst episodes of my morning sickness as I vomitted about 11-12 times that day. The culprit that trigger my nausea is actually fish. As I couldn't keep anything down my tummy, I have to take dilectin to control my vomitting. Ever since, I have no appetite or interests in food. I can only take a little bite of the food and already feel full already. Is this normal? Will it affect my baby?
