What are my options for using contraceptives to control periods?

After extensive research and obsessive planning, I finally made the decision to get the Nexplanon in 12/2015. I've had extremely irregular periods which came anywhere between 21-38 days so it was very hard to track and predict when my next period would come. It was also incredibly long and heavy lasting from 7-9 days with 4-5 large pads per day. So I decided to go on birth control, not only that, I wanted to practice safe sex. I didn't want to go on the pill since I know I would have trouble remembering it. So I had the choice between the IUD and the implant. Needless to say, I got the implant. I was actually pretty excited to go on hormonal birth control, since I heard it could help reduce periods.

Fast forward almost 3 years, and my periods are still irregular, but in a different way. The first 6-7 months were spotting/light periods. I was ecstatic since I thought it was just beginning of a beautiful light/no period journey. Instead, starting 09/2016 periods started coming sometimes twice a month, sometimes not. I called the doctor and she told me not to worry about it and that some women take longer. Oct 2017 comes around and 2 periods a month have become the norm. And now, it is 09/2018, I'm making preparations to see a new OB-GYN, and their nurse becomes concerned about my double periods, but its been over 1.5 years since I've had to deal with this.

But is there anything else I can do about my periods? Maybe a combination of nexplanon and the pill?
