38 weeks are these contractions?

Alisa • Mommy of 2! Baby #2 due November 19th. Happily married.
I'm not feeling period cramps or back pain it's just a very very uncomfortable tightening in my belly has been happening stronger and stronger for weeks it's really bad when I lay down and try to sleep are these like real contractions or BH? They're so uncomfortable I have to move and they just won't go away and I lose my breath. I'm so miserable hahaha.
