Help Me, please.

the begin of January 2017 I got the nexplanon BC in my arm. I read that some side effects could be like weight gain and bad acne. From then to now (July 2017) I have gained a lot of weight and I already was self conscious,but now I do not feel any confident in my self.. and it's causing me to have very bad depression. I want to get it removed but I'm not 100% sure that's it's because of it. I'm not sure what I'm asking but any help will be appreciated. I just want to hear different side so I can decide on taking it out or not.
