Anyone else experience this and go into labor soon after?

So I’m 35 weeks today and all day I’ve had TERRIBLE back pain/cramping. I’ve also got the past 2 days had an increase in thick white discharge (no blood) I dropped at about 34 weeks. I think I’ve been having contractions but I’m honestly not to sure and I’ve also had this feeling in my pubic bone like I’ve stretched (that feeling after you workout when your sore) but I haven’t. Lastly I’ve also had this lightening pain in my vag. Is labor close by??
