29weeks losing my mucus plug


So today I went to the hospital because I was having light contractions every 2-3mons for 40-60 secs. My cervix was not dilated. But when I got home hours after being discharged. I used the restroom and noticed my mucus plug coming out. And it’s steady coming out. My doc said don’t worry doesn’t mean labor. But I’m still having pains in my lower stomach and pain in my back.
