Okay so yesterday I went to the bathroom and I wasn't having any discharge during the day or anything. And when I went to the bathroom I wiped and had a big string of mucus. I didn't think to much about it I just thought it was normal discharge. But I never had anything after that either. And today I've been having contractions off and on through the day. I'm only 28 weeks. Could I have lost my mucus plug? I have Braxton hicks contractions regularly so it's not abnormal for me to be having contractions. Should I go in to the doctor?
