i had a 2 week prelabour with dd, strong regular bh, a show over the 2 weeks.
That was 37-39 weeks

With DS i had strong BH from 20 weeks so i didnt go off it. But no show that time.He was born at 37 weeks

Both quicky labours...

so it may be just BH or prelabour. Very hard to say lol - sorry that isnt much help
