Rapid weight gain after you stop breastfeeding?

Annaliesa

I'm a FTM and I stopped breastfeeding about 10 days ago. Since that time my weight has ballooned and I've gained 10 pounds or so in that amount of time. Nothing in my diet has changed and I usually walk every morning before work. Is this normal? Will this weight go away or am I going to continue to gain? I haven't got my period yet but I am having severe cramps which I think it may be coming.. any advice or tips? I'm super emotional and feel like I have no control over my body anymore.
