Feelings before labor?

Kayla • E 11/18 💙 Wife 👰🏻 TTC #2

I’ve been having terrible lower backaches, a lot of pelvic pressure - so much so that it hurts to walk for more than a few minutes, peeing way more, lots of BH contractions, and overall, I just have a feeling that I’m going to go any day. Plus, (maybe TMI), but I lost a lot of my mucus plug when I was having sex the other day! At my last appointment (5 days ago), I was 1.5 cm dilated and 80% effaced. What did you experience shortly before you went into labor?
