Healthy eating problems..7w4d

Any other ladies having trouble eating healthy? I ate pretty well before my pregnancy but these last two months all i want is processed junk. I used to love celery and cottage cheese as snacks..now? No way. I gag at the presence of celery! ): I want so badly to nourish my baby with whole foods but i just can't. Mac n cheese has been my go to lunch and bagels for breakfast all week due to carbs being the only thing i can hold down. I really hope im not the only one! First doc appt on monday with my OB so i will talk to her then too.
