Period while pregnant

Lee • Mommy to 3 year old girl! Baby #2 joining us March 2016!!!
Since Tues I've had what is a little more than spotting (so this is day5) but not near as heavy as a period (I haven't had to wear a pad or anything). I would live to hear stories of healthy pregnancies with this kind of bleeding. 
I went to the Dr on Tues and they said my cervix is closed. I also got to see the baby and hear the heartbeat. I'm just concerned about the next few weeks if this keeps up!
