Miscarriage then missed period - HELP!!!

Shelby
Hello all! Last month I found out I was pregnant then within 2 days starting bleeding. I found out I was miscarrying very early. They did an internal ultrasound and my uterus was empty. They said after I stopped bleeding I should start ovulating like normal. 
My husband and I were trying all of January and into February. I am normally never late on my period - in fact I started miscarrying a few days after my period was supposed to start. Now I am 2 days late but I have taken 2 pregnancy tests and both were negative. 
I am so frustrated with my body and with being confused. Anyone have any insight or a similar experience? Please share!!!
