I'm 37 weeks tomorrow and I'm starting to have some early signs of labor!

I know it could still be a few weeks, but these things didn't happen until right before I went into labor with my first 2 kids.

I'm losing big pieces of my mucus plug, I'm having menstrual like cramps/backache and I've been having contractions for weeks.

I've had a leep procedure before this pregnancy and I'm curious if anyone else that has had one thinks it made labor start earlier? I didn't go into labor with my first 2 until 39+1 so I'm just curious!
