Thinking about getting pregnant

I am 1 year out of RNY and truly enjoying my new life in a size 5/6...

I have been in a long distance relationship for the past 6mths with an amazing guy.  He is not aware that I was overweight or that I had this surgery; I have all intentions of telling him just waiting for the right time.... My question however is that he would like to have a baby with me in about 2yrs(it's part of his 5yr plan)... I am terrified of regaining weight from the pregnancy. I was so set on not having anymore children during this process that I blocked out anything to do with pregnancy in the teachings I went to, now I wish I would have listened...lol.... I know 2 years is a long time but can some people that have been pregnant after RNY share their experience with me...how much weight gained in pregnancy? any pregnancy complications due to surgery? and losing pregnancy weight after pregnancy? and how is your pouch post pregnancy...eating more or less?

thanks!
