Worried and wondering if I should go to the doctor

So, that I’ve noticed, since I was maybe like 16 or so, (I’m 26 now) I have had some sort of problem with eating in general. I am pregnant with number 3 and my last baby, and It has been a real battle for me because i get sick if I miss a meal a day or if I slack and eating things I without any source of protein or any carbs. But the truth is i hate eating, i hate the taste of most food, not only cause I’m pregnant but it’s been like that for awhile, (more so now of course) that’s why I’m worried. I love cooking but I barely eat anything and it affects my health. What do you all think it is? I know it can’t be anorexia because I’m not skin and bones. But I’m on the edge of being anemic my doctor said.
