Implant and sweating more than usual

First year and a bit on the implant absolutely perfect. Minimal periods and literally zero side effects. However coming up to year 2 I started bleeding a lot on it. Almost every other week I was getting my period. My GP recommended I get a new one fitted and sadly from the beginning I’m still having frequent periods and ache. It’s a real shame as I really enjoyed having it at the start but I will be switching now.

I’ve had this implant twice now both times had side effects I couldn’t deal with first time I gained nearly 3 stone and this time I’m on the weight loss injection and it seems to be countering the weight gain but honestly I’m so emotional and insecure my partner is struggling to deal with my emotions and so am I

Stopped my periods for the first 4 years then they became heavier - lasting up to 3 weeks
