Implant and nausea or vomiting

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.

I gain weight and got chronic fatigue. It was awful.

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!
