how do I know when I'm contracting? I'm in pain right now

Are you timing your contractions ?

Does any where else hurt like your back ?

my pelvic Area hurts and know Idk how to @ashersmommy04116

I lost my mucous plug yesterday night and I been Cramping but until now they've gotten a little bit worser which means they hurt me more @ashersmommy04116

There is a very good possibility you are in labor .... especially being 40 weeks. I would call your midwife or 24 hour nurse .... its better to be safe than sorry.

I am thanks @ashersmommy04116
