This is my first pregnancy. I started getting owning sickness at 4 weeks pregnant, it has become progressively worse. I am now 6 weeks pregnant, struggling to eat anything but chips and just keep vomiting. Today I have Vomited 4x. Is it normal to feel sick all the time and not be able to hold anything down? I'm worried that my face looks thinner and the baby isn't getting the nutrients it needs to grow healthily
