Real or fake labor?? I can't tell :/?

I know it's silly to be asking this question :p but i really cant tell. I'm 39 weeks due in 4 days!.. 1+cm and 80% effaced. I had my membranes stripped yesterday. Now i'm experiencing contractions with period like cramps in my lower back I'm trying to time them but i'm not doing a very good job lol. & i'm so used to braxton hicks I cant tell if im in labor or not...
