Help please...

Shaye
I had my 39 week appointment this morning (I'm due Saturday). She checked my cervix & I had some light bloody mucus the next time I went to the bathroom. I've only had this happen once before. I just went to the bathroom again (it's been about 4 1/2 hours since she checked me) & I'm bleeding & there's no mucus. Should I worry or is this normal?
