Weight loss to get pregnant

So I am overweight and am trying to lose some weight so that I’m healthier and also have a healthier pregnancy. I’ve lost about 8 lbs now (taking it slow) and am still TTC while losing. We were have been trying for about 4 months now and nothing. I’ve only been trying to lose weight for about a month and a half. Anyways... has losing weight helped anyone else to get pregnant?
