I was like this at the beginning.
Not to frighten you, but I've only just got my appetite for veggies in the last couple of weeks.
Try and make things as easy as possible for yourself with the veggies etc. Get ones that don't require much effort if you can't bring yourself to cook them.
I struggled with cooking them mostly and so would have things like toast for my dinner.
Are there any which don't make you gag? Try and eat those instead, I craved sugar/carbs massively so I would have bananas and custard or add fruit to my porridge in the morning.
Failing that, get yourself a good pregnancy multi vitamin.
