13 weeks with TWINS

Hey y'all, 

 had the gastric bypass on August 14th 2012 and I know that this is something silly to be worried about but I worry about gaining to much weight with this pregnancy. I went from 411 to 256(PP) . I went to the dr yesterday and I am at 269. I know that I am going to gain more because of having twins but is some of it in my head? Head hunger? I have also quit drinking my protein shake as I was told that I can no longer supplement a meal with them but I can drink them in between for a snack. Does anyone have any advise? I am not looking to be bashed on or told that I am stupid for not waiting. I am simply look for advice. How many calories should I be aiming for each day? .

- Ohh I will add that the dr said that with twins I should gain 40 to 50lbs and has not said anything about my weight. 

Every Pregnancy is different. With twins you are going to gain more. I would say keep your intake at a point you can handle... unless the babies are suffering... then up your intake. I had to eat every 2 hours with my pregnancies.

With my daughter's pregnancy I gained a total of 10lbs. My son however in the last month I gained 20lbs.

I lost all my baby weight and more after I had them. Good Luck.
