Anyone else go through the same thing?

Sarah
I need a little encouragement and just wondering if anyone else has had this same thing happen.  I am 6w4d and yesterday I started bleeding.  It was light pink yesterday, and today it's a brownish pink.  I started bleeding after having sex yesterday morning.  Anyone else have this same thing happen and still have a healthy pregnancy?  I talked with a nurse this morning and she said just to keep monitoring it....to make sure it doesn't turn to a heavy flow.
