Mucus plug.. 26 weeks and 4 days

I'm 26 weeks & 5 days and today I stared loosing my mucus plug. Read online that's normal and it would regenerate itself. I called L&D just to make sure and they said if baby has decreased movements, if I have pain, bleeding, contuined mucus, contractions, or anything to come straight in.. Baby girl started moving like crazy after that happened. I haven't had any contractions or anything but I noticed I started having period like leg cramps. I read online to drink water and they should go away and they did not.. I've been having back pain with this as well. I thought it was just normal since I always have back pain but when I woke from my nap I noticed it was more achy and low and the leg cramps are definitely still there. Anyone else experience this? It's past midnight and I plan to call my dr but I am unsure of what to do ifthis continues  throughout the night
