How much should I really be eating during twin pregnancy?

I need help because I'm worried about gaining too much weight too quickly and I've seen so many varying things out there about calorie increase during the first trimester with twins.

I'm 10 weeks pregnant with twins and I feel like I'm eating significantly more than I did before I was pregnant but I'm SO hungry so can someone please just gut check this to tell me if I'm eating too much or not enough? I did not count calories before my pregnancy (and dont count calories now... i have a history of an ED many years ago so its a toxic cycle if I start again) so really dont know how to gauge if I'm eating the right amount.

Before pregnancy I would usually skip breakfast because I wasnt hungry and have a latte for "breakfast." When I got hungry around 11:30 or 12 I would eat a sandwich and maybe some chips on the side or something. For dinner (around 6:30 or 7) I would eat a larger meal like chicken, rice and salad or pasta. I would usually end with a small sweet treat at night before bed.

Now this is what I'm eating

• latte or matcha latte in the morning
• smoothie for breakfast around 9am
• lunch around 11:30 or 12 (usually a sandwich and something on the side)
• snack on nuts or something around 3pm
• Dinner around 5:30 because I cant make it any later becuase I'm so hungry - usually salmon, chicken, pasta, or whatever and a side salad
• Something sweet before bed
• Sometimes I wake up in the middle of the night SO hungry that I have to snack on whatever I have around to make it through the night

It just feels like so much food compared to what I was eating before and I'm still only in the first trimester - but IM SO HUNGRY. I'm not sure exactly how much weight I've gained because that's another thing I dont track for my mental health sake... but my hips, butt and thighs feel bigger and clothes feel much tighter.

Also please no comments on the ED piece - I've been through years and years AND YEARS of therapy and am in a very good place now. I'm okay with gaining weight during the pregnancy... I just dont want to gain too much weight that it causes negative effects to me or the babies. Thanks!
