My mom didn't get them either...but I sure did!!!!! My first baby was pretty big for me. When I got Pg with him I weighed 104 lbs. I gained 50 lbs with him and he was 8 lbs 11 oz. I didn't get stretch marks until the last month. I was so excited because I didnt' have one....until the very last month...I guess he was getting so huge....OH well...not much I can do about it now! LOL!!!
