Mucus plug or discharge??

Alex • Mommy to a 2 year old little girl!
FTM and I've been put on bed rest since 30 weeks, currently 32 weeks. I have a short cervix and was experiencing Braxton hicks and her head is really low. I'm wondering if this is Normal discharge of could I be using my mucus plug?? I'm not sure what it's supposed to look like!
