Delusional, really? How unsympathetic and condescending. This person wasn't pregnant.
What is the mucus plug?
The mucus plug is just what it sounds like, a plug made of mucus. During pregnancy, the mucus plug develops and lodges in the cervix to block the cervical canal. Its job is to protect your uterus from unwanted bacteria and pathogens that could enter in, like from sexual activity or vaginal exams.

It's most likely Plastic Bronchitis. This is something most family doctors won't be able to recognize. It's best to seek a pulmonologist to confirm this.
