It can definitely happen! Hubby and I tried for over ten years. Just when I had lost all hope (due to a miscarriage) we got pregnant with twins. It was a scary pregnancy because we were worried we'd lose one or both babies. I'm happy to report that our boys were born health at 8 months. This week the boys will be 10 months old. I had a unfill at 4 months of pregnancy due to morning sickness. Don't lose hope and just focus on yourself and your weight loss. I was banded in 9/30/2009 and our boys were born 10/23/2011. Feel free to contact me if you have any questions, I'd be more than happy to answer any questions/concerns.
