Is there a reason why you need to have a kid ASAP? If you had to wait another year while you lost weight at a reasonable rate, would that be too late?
It's possible that when you lose some more weight, you'll get pregnant naturally, because fat can throw off your hormone levels and make you less regular and make it harder to conceive.
That, and stress makes it super hard to conceive! Many couples find that when they quit trying to have a baby, and go back to having sex when they want to and because they want to, boom, baby! (Might have something to do with the fact that a female orgasm noticeably increases a woman's chance of getting pregnant; those can be hard to come by when you're under stress!)
Have you figured out how much weight you need to lose to drop down to the appropriate BMI? (And, if you show your doctor that you've been steadily and dependably been losing weight, he might okay fertility treatments, even if you're still a bit over the preferred BMI.) Your goal may not be as far away as it seems.
For example, at 5'6" and 200lbs, you would have a BMI of 32. But drop just 20 pounds and you'll be at 29.1--probably good enough for your doc. If you're 5 feet even, then you'll be at 32 BMI when you weigh 163 lbs. But lose just 15 lbs and you'll be at 29!
If you can lose a pound a week on No-S--something that seems to be pretty common for people with a good bit to lose--then it's just 5 months to lose 20 pounds. Not an eternity at all!
(And if you've been doing No-S faithfully for the past few months, you may be closer to your goal than you realize.)
Also, if you're not doing much exercise, take that up to help speed up the process a bit. Strength training can help a lot, because while muscle weighs more than fat, it takes up a lot less space and it constantly burns calories. Toning up can make you appear thinner (which may sway the doctor in your favor) and it can help you lose more weight over the long run, because it increases your metabolism. (Exercise also helps regulate hormones and decreases stress--another baby booster!)
You know that if you go on some crazy diet, even if you lose enough weight to qualify for assistance, you'll feel bad, you won't have the best health going into your pregnancy, and your eating habits will get so out of whack, you'll go right back to that stress eating and gain more than you lost.
(Which is why it's stupid to set medical treatments based on a somewhat arbitrary number, but that's a soapbox for another day.)
Get back on track with No-S, add in exercise (if you're not doing it already), and come join the daily check-in board to keep your spirits (and willpower) up. Weigh yourself once a week and see about how much you're losing. If you're doing a pound a week, then make yourself a doctor's appointment 5 months out (if you have to, tell your hubby that's as soon as you could get!). That will also help keep you out of the snacks and running down the lane (or whatever you want to do for exercise). And I bet by the time you go to the doctor, he'll be willing to talk to you about your fertility options.
