Weight loss sugery and Want kids

So I've been a big girl all my life, not to mention my boobs are huge like I'm a 44G I'm 5'3 & 250 I want too loose weight so bad but It seems impossible to drop anything I work out an I just seem to maintain the same weight. I have been seeing the fat doctor lol an they told me we can look into weight loss surgery. My thing is in future I would love to have kids now if I go ahead with surgery will this effect me in future? HAS anyone ever gotten a this done before an had kids after if so which surgery did u go with. Tell me ur story please
