Transvaginal Ultrasound, please help!!!!!

Just
I had brown spotting couple days ago, and i went to the emergency room to check if everything was ok, they did transvaginal Ultrasound on me, after they said everything looked ok, and that its ok to spot sometimes during the first two weeks. After i got home, i started bleeding with bright red... Did anyone have the same problem? And how long did it last for?
