Labor soon?

Zai • 24. parent of one 7 year old girl with a little boy on the way
I'm due Monday [so excited!] and just lost my mucus plug. I'm 3 cm dilated and 70% effaced. Baby's head is engaged and I've been having alot of BH contractions. This is my second baby but it's been 7 years since my first and I don't remember a thing about the first one, haha. Could labor be right around the corner for me?
