Missing periods

Hi all,

Wonder if i could get some advice... my last period was on January 13 2018 and I haven’t had one since, I’ve always had irregular periods but not this bad. Been to the doctors for hormone tests and all came back okay. I also had a camera a couple of years ago (as I lost a lot of weight and my periods went missing then, but came back) and my ovaries were healthy. I’m a healthy weight, eat well and exercise. Anyone have the same issues?
