brown discharge

Stacey

I am currently 9 weeks 1 day. I had my first ultrasound a week ago on Friday. since Sunday in the morning when I pee I have some brown discharge when I wipe. It then goes away for the rest of the day until the next morning. is this just from my transvaginal ultrasound? I have small cramps here and there but have had them the whole time so far. my dr said they are normal as your uterus grows and stretches.
