Bloody Nose

Jordan
I have had a bloody nose the last 2 nights around 8-9pm... but tonight it was fairly bad! My nose was bleeding for about 7 minutes and then I coughed up a thick mucus-type thing of blood... and then my nose stopped bleeding. Anyone else had this?! I'm almost 33 weeks pregnant... I know that my doctor said something about  your body making so much more blood while pregnant... Helppp!! Should I call my doctor?
