37 weeks, mucus plug, gone. Help!

So I'm 37 weeks on Monday morning, I just lost my mucus plug and I'm still actively losing it as I type. (tmi, sorry) I had an appointment today where OB said 60% effaced and almost 2 cm dialated. Heavy back pain all day and there's so much pressure. It literally feels like I need to pop my belly to relieve pressure. Based on your experiences, when do you THINK I should be expecting labor? Period like cramps but no noticed contractions. I've been cleaning and rearranging for two days now. Lol This is my second child. My first son was born 36 w 4 days. Just wanting opinions! Please no negative comments :) thank you!
