Eating enough

Anyone else having trouble eating enough? I'm slightly overweight so for the last year before pregnancy I was eating at a calorie deficit (healthy eating) and working out to try to lose weight. I've lost 35lbs this year but now with pregnancy it looks like I should be eating around 2200 calories a day and I'm having a hard time now INCREASING and keeping it healthy...also my appetite sucks a lot of food is grossing me out so that doesn't help!!
