Transvaginal ultrasound

So I’m 6w3d and I got a tranvaginal ultrasound earlier and I showered and everything it’s like 4 hours later and I go to wipe and there is brownish discharge mixed with my regular discharge so I know it’s dried blood. Is that normal after a transvaginal ultrasound? I’m sorry I don’t have family or friends to ask because no ones knows and im freaked out because I’ve been spotting once a week since finding out I was pregnant.
