How to avoid early labour???

I'm 36+5 and I've tested positive for group B strep. I heard this can bring on early labour.

As much as my body is hurting and I am fed up with feeling like rubbish and not being able to get comfy, I could do with another couple of weeks before the baby makes their appearance!!

At this stage, most women are asking for tips to bring on labour but does anyone have any tips for preventing early labour??
