@ambiibambii, are you dialating? Effaced? If yes it could be early back labor... Maybe. But you should check with your doc to see if they want you to come in

even if I'm already dilating? @mrslawless

@ambiibambii, at 35 weeks... The most likely scenario is straight up back pain. Your baby is big enough your balance is off and it's harder on your back. The random cramping could be Braxton hicks. Try putting some heat on your back.

I have constant back pain but there are times when I get cramps and it gets worse @mrslawless

Depends... Is it just constant back pain? If it's not coming and going at all you probably just have back pain.
