Need a bit of advice/support

So I don't have a lot of support when it comes to losing weight. Everyone in my family is overweight/obese except for my younger brother who is incredibly fit. My husband is super skinny but eats like a horse (and not a lot of healthy food). Everytime I mention wanting to lose weight they tell me "you look fine, you don't need to lose weight." Especially my husband. I'm starting to think he likes me this way, but I don't.

Anyways, he wants to try for another baby this month, and I'm okay with it. I'm still breastfeeding my daughter (she just turned a year old). When I was pregnant the first time I was very careful about what I ate, now I've gained probably 15 more pounds since she was born. My husband said he would let me sign up for a weight loss program after we have another baby and that he would pay for it and everything, even though we don't have a ton of extra money. I want to lose weight now though, i just don't know how to do it safel while breastfeeding and pregnant. My doctor said it's okay to lose while while pregnant. I just don't know. And I don't have any motivation or support when it comes to exercising. I don't have any really good healthy recipes that would help, and I hate stuff like peppers and onions, they make me gag.

Does anyone have any suggestions? Meals, motivation for exercise, anything. Anyone going through the same thing that needs a buddy? I'm desperate.
