I am about to get Nexplanon,the birth control, I decided to read and saw all these side affect``s. I am a smoker and I struggle with depression,I am 21 years old and have twins with my husband and we don t want more kids, this seems to be the most effective method of birth control but now I am stressed.would you suggest nexplanon or something else, I don t want a common weight gainer, or a pill and it needs to stop ovulation due to cysts, it feels like nexplanon is my only option
