Nexplanon implant and irregular periods

When I first started this birth control, I had a period for three months on and than it stopped for three months and that cycle continues into my second year where my periods got more regular like normal. Now in my 4-5 year of use and getting a fresh implant i do not get a period at all. I also noticed a significant amount of weight gain when i started on it about 35 lbs.

I give it three starts because it was effective as far as me not getting pregnant but I couldn’t deal with the spotting and I bled almost every day, granted I didn’t keep it that long but it was miserable to bleed every day since insertion and it was the ultimate reason for it being removed.

Nothing worked prior to the implant…3 conceived while using another form of controlled release birth control, and my last 2 were planned by getting the implant removed. My periods are somewhat irregular but also extremely lighter than before and shorter lasting, however I have noticed every other month that it’s rougher than before, cramps, headache etc. but then 19 days later it’s just normal. I’ve also been able to maintain the same weight while using the implant and regardless of changes in my lifestyle that would suggest a fluctuation in weight over the last 7 years
