Idk what to do...

So I've had spotting two different times withing a week and half and when I called my Dr they acted like it wasn't anything to worry about. I called at 8am and asked if I could be seen this last time for my peace of mind because I had a miscarriage in December of 2013 and I am kinda on edge ? my first symptom was brown spotting then when I lost my baby.  they ended up calling me back at 4:15pm and said that it's normal to have spotting and if I'm still concerned I should go to the urgent care....is this normal for a Dr to not really take much concern in their patience or am I just so nervous/worried that I'm overlooking?
