Am I in labor ?

Trakiya • I'm 23! First pregnancy, It's a boy !! His name is Kohen Jean 💙
So i started having some cramps at 7 something am nothing too serious. Then around a little after 10 am I went to the bathroom and seen that I lost my mucus plug (had my bloody show) yesterday 3/20/16. And started having cramps again around 10pm or so. They have been on and off since then for about 20-25 min or so each contraction lasting about 45 seconds- to 1 min. My water hasn't broken but I feel the pain in my lower stomach? I'm a FTM
