Implant 2nd round. HELP!!!!!

Rebecca
I had the implant about 3 years ago and I bled very heavy every day for 5 months straight. Tried other contraception but it just doesn't help, makes my mood swings and everything worse... Going to try the implant again but I'm scared that my body is going to have the same reaction to it. 
Has anyone else ever done this twice and had different side effects the second time around??
