Why?!?

Went to the doctor yesterday and she told me my cervix was soft, I was dilated to 4, and I was thinned out. I had my membranes stripped (cervix stimulated). Today, I walked (a lot), I cleaned house, I was on my feet pretty much all day.. And then I had sex...I lost my mucous plug already too.... 
Why am I still pregnant?!?!?!?! When will I go into labor?!😩😩😩😩
