Question for ultrasound tech

So whoever is an ultrasound tech. I just ha my mirena checked. It's still in place . But my stomach is getting bigger I am having all the symptoms I had with my last baby. My stomach is getting big and round. My husbands mom got pregnant with the mirena in place. Can y'all tell if I'm pregnant with the mirena when y'all do a vaginal. Bc I have this overwhelming feeling that I am .
