late period

I had a very early miscarriage August 19th which was when my cycle was due, according to my dr's my cycle should have stayed on track. I've had pregnancy symptoms since September 10th but took my second test today and it was negative. I'm 2 days late, my hips hurt, my breasts feel horrible, I've been nauseous and so tired everyday. I'm going to the bathroom between 16-25 times a day it's insane. I keep telling myself I'm not but my body says otherwise. The tests say not. Any advise? I don't want to take another test but i can't push my gut feeling and symptoms away. I'm not having ghost symptoms those all vanished once the bleeding stopped after the miscarriage, returning the 10th if my cycle was still on track I would have been ovulating the first few days of September.
