Hello, I’m at 17 weeks now too and found it super hard to eat anything just a week ago. Now things are better. However during the earlier weeks when all I could stomach were plain carbs, I would blend a smoothie with milk or water or coconut water, veg, frozen fruit, chia seeds and nut butter. I used lots of frozen berries to keep it fresh. I could usually keep that down. Anything else with meat or fish or too flavourful was absolutely a no-no. Hope this helps :)
