Cramping?

Yesi
I'm 36 weeks & 1 day. Last night I kept having period like cramps on & off all night. What does that mean? & baby boy has definitely dropped now! Today I have my dr's app & I will be getting checked for dilation. 
I got checked when I was 32/33 weeks because I was having contractions, but at that time my dr told me my cervix was barley softening. I'm praying I'm made progress today.! *Fingers Crossed*
