Birth control implant vs Spermicide

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?

I have had the implant inserted 3 times. First 2 times barely had a period here and there. Always had one for a little longer right after it was placed. But the last time over a year ago it was fine until the last 4 months. I have had a period about every 2 weeks. Starts stops, starts stops. Not sure why but super annoying. Better than the pill and having a pregnancy. My kids are grown. My period has always been 28 days like clockwork. Wish I could not have the sporadic spotting but what do we do??🤪.
