Post Op Fears

Hey All, Something has really been on my mind lately so I thought who better to ask than you guys! I am post op just over 3 years. I've lost 150 lbs and have a bit more to lose but am very content with where I am at. I'm 23 years old and live in Colorado. I had a lot of complications after surgery. Currently, I am still dealing with some. I have a pretty bad iron deficiency that I'm trying to get under control as well as an ulcer that bled recently and landed me in the ICU for a week where I received two blood transfusions. I have gall stones which don't seem to be a big deal yet. I also may need further surgery to deal with the ulcer. I recently had all my vitamins checked and I was good in everything but iron. My fear is about pregnancy. I have an incredible boyfriend who I've been with for 2 1/2 years and knows all about my surgery and everything that comes along with it. He is amazing and understanding. We are planning to get married after I finish law school next year. I'm not planning on having kids for quite awhile (at least another 5 years) but my fear is about whether I will be able to get pregnant, but more importantly, have a healthy child. I'm pretty good about taking my vitamins and especially have concentrated on taking folic acid (which I read to be one of the main causes of birth defects). I'm just scared that I won't be able to have a healthy child.  Have you all had success? Have you found the pregnancy tough? Did you have any concerns of your own? Any stories or words of comfort would be so helpful! It is obviously one of my desires to be a mom and raise a family.  Please share! Steph
