Is my body preparing for labor?

I'm 37 weeks and for the past few days Ive noticed my body is acting and feeling a bit different. I've had a huge increase and change in my bowel habits (sorry TMI), my hips are very sore as if the baby is forcing them open, lol, she has def dropped lower, my breasts have been leaking, I'm extremely irritable, ALOT of contractions (still irregular tho) and Ive had a ton of vaginal pressure. I've never went into labor on my own, always been induced so these feelings are all new to me. Is it in my head or does it not sound like my body is preparing for labor? Im not guessing it will be anytime soon, but I'm guessing within the next 10-14 days. Dr said last week she was surprised that the baby was already in position. I'm also measuring a few weeks ahead. Maybe all this is wishful thinking but I'm just getting excited!!
