Implant and lower back pain

I have attempted trying the implant twice. Once when I was 18 and recently at 25 after having a baby. Whilst insertion is quick, easy and pain free with local anaesthetic, the effects of the implant on my mood have been detrimental. The hormone caused me on both occasions to develop severe anxiety and depression almost immediately after insertion, as someone who doesn't usually suffer with mental health issues. It's like having PMS but on an extreme scale. The implant on both occasions made my life miserable. I had to have both removed early and funnily enough a week or so after I did, I felt like 'me' again. The implant has a massive amount of hormone in that runs through your body daily. A hormonal coil works much better for me as it has almost 1/6th the hormone amount of an implant which is mostly contained within the uterus.

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
