5w3d advice needed please

Ashley
I had a transvaginal ultra sound last night at the ER.
Tonight, 24 hours later, I just wiped and saw light pink blood and in the toilet was a clot which was bright red. About the size of the dime. I've had some light cramps today but nothing too painful. Can someone tell me if this is likely caused by ultrasound or is it a miscarriage?
