Nexplanon implant and periods to stop

Well I would like to speak to somebody what does it mean when I been on birth control when It ended my five years but keep forgetting about it I'm about 4 or 5 years over an still haven't taken it out please can y'all contact me an let me know if that really bad actually it might even be more than 5 years over mabe like 6 or 7 or 8 years over what isn't good or side affects or is it messing up my insides I need to know theses things please?

When I first started this birth control, I had a period for three months on and than it stopped for three months and that cycle continues into my second year where my periods got more regular like normal. Now in my 4-5 year of use and getting a fresh implant i do not get a period at all. I also noticed a significant amount of weight gain when i started on it about 35 lbs.

Nexplanon was effective as far as preventing pregnancy. However it has caused sharp pains in my head and heart, increased pulse, high blood pressure. Anxiety, depression, hopelessness. Swelling in my legs up to my knees. Huge weight gain and difficulty loosing weight. It has slipped and hasn’t been found. Sleepless nights, due to increased heart beat at night. An adrenaline attack only at night.
