Appetite loss in second trimester?

I have been eating. But getting full faster. In the first trimester I was hungry as soon as i woke up. And hungry most of the day.. I gained 4 kilos which is 8.8 lbs!

Has anyone else been experiencing this?

I am already overweight. I would be fine not gaining any more (ha ha ha)

In my first pregnancy I gained total of about 70lbs! I would be more than happy to gain the 30 lbs recommend (or less since I am overweight )

Do you think the appetite loss is in my head since I know I am heavy? Or is my body simply not needed as much fuel?

P.s. I do try to eat healthy. But will eat take out probably more than I should.

Sorry it's so long!!
