Weight Loss Pills

Ashley
Hi! I am STRUGGLING with my weight loss. I eat my calories, don't eat late, drink a gallon of water, and work out five days a week. I lose a lot some weeks and then others it's like I either don't lose or lose a half. I was thinking of incorporating a weight loss pill such as Alli, Hydroxicut, or Slim something. Any suggestions? How will this affect me TTC?
