2 months in and still not gaining weight. Anything makes me throw up, smell of hamburger, taking my multi vitamin

Try super plain foods! I know I had an issue with most foods, smells and meats in the beginning and lived off of plain mashed potatoes or plain pasta noodles with butter :) I also always take my prenatal vitamin right before bed and with a small snack! I find they still upset my stomach. Hope you start feeling better soon!!
