Birth control types

Hannah
Hey guys so I need some oppinions. I'm thinking about switching from the implant to another type of BC. I've gained weight and it's really been tough. I'm not over weight but it's just made me feel less like myself and I've felt fat. If that makes sense. I'm looking for a safe type of BC that won't make me gain weight I've been working very hard to get the weight off and nothing seems to help. any opinions or suggestions would be very helpful.
