What’s going on

Hi guys so I havnt had my period in 3 months. I’m definitely not pregnant I’ve had ultrasounds for other things and that has also proved I’m not pregnant. I got the implant in my arm around 2 months ago. I was on the pill before hand. When I took my last sugar pills it never came then I decided to change to the implant and yet still havnt got it. Yes I know some people don’t get there periods on the implant. But I’ve had the same type of implant last year and I got my period.

I just wanna know if anyone knows anything about this.
