Implant and sweating more than usual

Whilst the second and third years on the implant mellowed me out a bit as a mentally unwell girly (struggle to regulate my emotions), the first year was pretty bad now I look back on it-i was quite depressed although unsure if this was due to the implant. I never had any periods, except for some rare light spotting for a couple of days every 6 months or so. No other symptoms really except for some weight gain and boob enlargement. My libido was a bit lower as well imo.

It was good for the first implant but then when my second one was fitted I bled for almost a whole year and became very exhausted

It was my first time on contraception, I was afraid to forget the pill and had the feeling that the implant had less hormones in it. My mood was very fluctuating for the first 4-6 months but then settled. My period was much lighter at the beginning and not painful for the first few months, then actually got irregular after 7-8 months (only a few days, then nothing for 2 weeks, then 3 weeks long period...) The insertion of the implant was very easy and not too painful, been able to feel it since the beginning.
