If I were you I would wait a while and work on the weight. Any reduction improves your odds in pregnancy, even if you don't achieve your final weight loss goal.
At your age, another year or two will not significantly alter your risk but losing some weight can have huge benefits. But, if you don't actually work on the weight loss, combining obesity and age over 40 would increase your risks.
So if you are serious about a healthy pregnancy with lowered risk, do something NOW to lose weight. Even lap band surgery can make a huge difference in pregnancy if you can afford it. Outcome of pregnancies following gastric bypass and lap band surgery has been shown to be better than outcomes in obese pregnant women. Nutritional status is important so taking good vitamin supplements after such a procedure is imperative. It is also encouraged that the surgical weight loss patient achieve their goal and level off before becoming pregnant and they are encouraged to wait for a year following the procedure.
Other options can be just as beneficial. Weight Watchers and other guided weight loss plans along with exercise has been shown to be very good prior to pregnancy. You may even wish to see a doctor at a preconception visit to discuss options because there are also medically supervised methods for a more rapid, yet safe, weight loss.
Congratulations on your desire to have a healthy pregnancy. Good luck with it.
