Nexplanon implant and irregular periods

It cause me to have my period for 145 days straight starting two weeks after getting it. The first month was honestly horrible with severe cramping and lower back pain while passing relatively big clots. It also made my mental health decline significantly during this time but after the five month mark I am feeling great and not pregnant!

I was on it for coming up to 8 years overall obviously great to not get pregnant and I was on contraception before where I had an accident so it was really easy and really quick to not have to think about this. It did really impact my moods and I eventually ended up having PMDD because of the severe mood swings. I would also bleed twice a month instead of just a once And it caused a really bad loss of libido and federal dryness. But these are all things that would probably happen if I was pregnant anyway.

My mood was completely changed on this contraception about 2 weeks in. I started getting really angry at everything/everyone very fast, I had a short temper, I felt sad all the time and like everyone was against me. Overall I felt I was going crazy and could not control my emotions at all. Also I had a constant heavy period for 3 months
