I have a 100 pounds to lose

Hi I'm Veronica and I'm new to Myfitnesspal I have 100 pounds to lose I'm down 27 pounds but having a hard time getting back on track. I want to get healthy and be able to be happy in my own skin. I'm a foster mom to a 3 year old little boy I want to be able to chase him without being out a breath and would love to give my husband a baby we have been trying for a while but due to my weight I'm having a hard time getting pregnant. If I can get some support I would really appreciate it or advice I promise not to waste any of your guys time . I hope to get to know you guys.
