Baby weight

I have gained weight since having my daughter and I've tried different antidepressants since my doctor thought they were causing the weight gain to happen so quickly. I didn't get my period till my daughter was 12 months and ever since then I feel like I'm losing weight now. Is that normal? Would having my period help my body lose weight?

Maybe it's just all in my head, I'm too scared to jump on the scales. I am breastfeeding so maybe that's the reason for the weight gain also.

Any advice on losing this baby weight would be greatly appreciated also! No amount of exercise or diet will get rid of the weight
