37+3, Possible to have signs of early labour so much in advance?

Shikha
Hey folks - sorry for a stupid ques, I am 37+3 weeks today and i feel some sensations in my vaigna, its a bit like muscles loosening up, downward muscular currents, sometimes little pricks like needles, wondering if these are signs of somethhing coming up?! No mucus discharge yet , no water leaking yet, really confused why these sensations are happening, i was expecting labour to trigger after finishing 39 weeks😬
