Pregnancy mucus

Kati • Im Kati and Im expecting twins on June 18th, 2016 💜
So they said that we create alot of mucus while pregnant. I woke up this morning with a horrible cough due to mucus in my chest as well as mg normal morning migraine. Every time i cough it makes my stomach cramp up really bad and makes my head hurt worse. Does this happen to anyone else?
