is spotting normal for first trimester?

Karen
I was spotting light pink blood the other day and I went to the hospital only because I had a miscarriage 9 years ago and I wanted to make sure the baby was ok and they said it was ok. Then the following week o started bleeding heavier like a period. I went to the ob and they said everything looked good. I'm 11 weeks pregnant and I'm concerned about where is the bleeding coming from or if this is normal.
