Mucus Plug

Hey! (: so I'm currently 38 weeks and 3 days, and I took my toddler on a long walk this morning, while walking I did notice a few contractions but nothing to worry about. When we get back, I went to the restroom, and I noticed my mucus plug coming out. I had to go to the restroom a few times to wipe because it just kept coming out. Is this normal? For it to continue to come out?
