Gaining Weight on Birth Control

Hey guys ! This is my first time posting; I'm pretty new to the app. So I've been abstaining for the past year for various reasons, but I'm starting back at college in a month and  I'm thinking of becoming sexually active again. I always use condoms, but I'm hesitant to go back on the pill because everytime I'm on it I gain at least 10 pounds. I know that when used correctly condoms are very effective, but I'm just contemplating whether or not worth it to be on the pill also, or if anyone who uses alternative birth control (iud, the shot, etc.) has experienced weight gain. Any advice or opinions ? Thanks !
