I just randomly got a bloody nose on my left side. It's bright red and stringy thick blood.

Common. Bloody noses, bleeding gums, bleeding cervix are all very common in pregnancy.
Relax, pinch nose. It's important if you have a nose bleed to relax - if you are upset an elevation of your blood pressure will keep your nose bleeding longer. Sit, relax, lean back and gently pinch your nose. The bleeding should stop within 10-20 minutes. Avoid aspirin, Ibuprofen (advil, motrin) and Naproxen (aleve), as these increase the time it takes to stop bleeding.
