Period type pains in back?

[BeautyAndTheBump1]

I woke up at 3am last night to period / diarrhea type cramping/tightening, but in my back?? They were quite painful.

It didnt go on for long at all though.
I'm 33 weeks. Do I need to be concerned or is it normal? I have had quite bad lower back pain the last few days.

It sounds like braxton hicks. I'd keep an eye on it and if they start coming with any regularity then phone maternity assessment.

Yes sounds like braxton hicks - warm ups for the birth.

My contractions felt like period pains in my back. As the pp said, its probably Brixton hicks. Start timing them and call your midwife for advice. Even though they’re busy, really won’t mind you calling. Good luck
