Does this make sense ?

Everyone thinks I'm crazy for wanting to lose weight before getting pregnant. I'm currently 25 pounds heavier than I was last year.. I'm about 130 pounds but I'm 4"9.. I don't want to end up being 200 pounds after my second child which may seem shallow but that's just the way I feel. I weigh the same right now as I did the day after I had my son.. (and lost 20 more within 8 months and was the same size as before) If I gain the same amount of weight / lose the same amount of weight that would put me at like 140 after I have said baby ... All I hear when I'm going to the gym is "idk why your trying to lose weight just to get fat again" it's really pissing me off !
