Period cramps? Is labor coming?

I will be 37 weeks tomorrow and for the last couple mornings I have been woken up by cramps like I'm about to get my period. They come and go kind of like contractions for a couple hours then go away for the day. I have yet to lose my mucus plug and Idk if I'm dilated at all. Also I don't think baby 'dropped' .. I do feel him pretty low and have quite a bit of pressure but my belly still looks high.

Does this mean I'll go into labor soon?
