Weight Gain?

Megan

Question for all: what is the expected weight gain for twins for a mother with a high bmi? I'm was 288 pre pregnancy, and I've lost 10 pounds which I hear is definitely normal during my 12+6 time with lots of nausea and vomiting. Before my Dr knew it was twins she suggested weight gain of 10-15 lbs, but hasn't mentioned different parameters for twin pregnancy. Thoughts?
