could this be the end?

38 weeks today, been loosing my mucous plug over the course of 3 weeks now and woke up to my belly a lot lower than yesterday! This is my second pregnancy, I had my first daughter 7 years ago. From what I have read second pregnancy baby drop usually happens the day of or few days before labor begins! Getting cramps on and off and a slight back ache when I'm standing up. I'm really hoping the end is in sight! Anyone else have similar happenings???
