39 weeks

Went to the drs due to me not feeling my baby move as much or as hard. I have a appointment for tomorrow for ultrasound and nonstress test. I was 1 and half cm dilated last week, cervix was still kinda hard and baby head is low... like my pubic area. and he stripped my membrane today. It didnt hurt and no bleeding. I cramped for alil bit but there gone now, having alil pains right under my belly.. what is that?. Back pains are still here. Does this mean it didnt work???
