I’m 39+1 and my back is killing me right now... it’s more on my right side which is where I feel my baby’s head is more towards. It feels like back pain from a period but 10000x worse and my stomach also just feels like bad period pain as well. It feels like I’m just having one long cotraction... could this mean labor is gonna start very very soon?

I have a chiro appt today and I might cancel it bc of how bad my back is, even tho that’s the point of a chiro lol. It’s not like an ache it just hurts so bad
