Am I in early labour?

Hi everyone!

I have had constant lower back pain since I woke up yesterday morning, around 3:30 this morning I had sharp pains in my back and had loose stools. When I woke up this morning, I had trouble getting out of bed because of how sore my back was. The pain has eased with the use of panadol but it comes back pretty quickly. With my back being so sore it's making it hard to walk and have just started getting cramps in my abdomen now that sort of feel like the cramps you get before your period is due just not painful, just uncomfortable. I have been getting what I think is braxton hicks, I never got them in my other 2 pregnancies. This is my 3rd baby, I was induced with my first and second. So I'm not sure what this is.

Does this sound like preterm labour? I'm only 34 weeks & 5 days.
