Birth control and weight gain/loss

Mo

Im 27 and was on birth control for about two years (microgestin and the patch) and. Have gained 30lbs. Currently I’ve been off for about three months and the weight hasn’t gone away. I’ve joined a boxing class, walk for at least 30min on lunch breaks and have lowered carb and sugar intake in my diet plus smaller portions and more vegetables.

Has anyone else had problems getting there weight back down to normal after BC use? And tips if you were able to?
