Finally going

I'm finally going to the doctor to see why I haven't had AF in 16 months off of depo. I've ovulated a couple times (confirmed with bbt and OPKs), but still no AF. I was told it could take up to 18 months, but my doctor went ahead and scheduled blood tests and a pelvic ultrasound. Starting a diet and exercise program as well hoping if I get some weight off it will help trigger it as well. Here's hoping nothing is wrong and I'm still just waiting for the Depo to clear my system.
