Is it possible that I might be going into labor early?

35 weeks/ about to be 36 weeks. I was having Braxton Hicks contractions. And then yesterday out of nowhere I felt pain in my lower back. Like I was in back labor. ( I had back labor last pregnancy and it was awful) but I was having that pain and it would come and go every two minutes for 45 minutes and then it just went away. She was kicking soooo much during that time. And is still kicking and jabbing me in the ribs. I also have the sudden urge to clean (nesting) which I didn’t have last time. And I’m having a lot of pressure on my pubic bone. I have a scheduled C section because I had an emergency last time. But is it possible I might go early??
