red bleeding after vaginal ultrasound?

I posted last week asking about spotting in early pregnancy. Well, I am still having brown spotting (for a week now), so I went to the doctor again this morning and had a vaginal ultrasound. The doctor said everything looks great. And my hormone levels from last week were great. She did see brown blood on my cervix. However, later in the afternoon, I had a quarter to a fifty-cent size amount of bright red bleeding. The doctor said to monitor it and see it if becomes a heavier flow. So far, it's been 2 hours and nothing more. So I'm hoping it was just from the ultrasound and speculum for the internal exam. Anyone else have bright red bleeding after a vaginal ultrasound / internal exam? 

Again, I'm from 1st tri, but wanted to ask here to get more responses
