Can someone give me a little help please clicking sounds 37+1w

K • 22. mum to baby boy :)
Im 37+1 weeks and for the last 2 days i have been having cramps and sharp pains in my lower stomach off and on but not a huge amount. i have been bouncing on an exercise ball since then to mive things along if they want too (baby comes when ready so whatever i do will either work or not depending on that). Today i have been having these pains quite alot but again not in a regular pattern but they dont stop when i move positions etc (im not dehydrated) baby has been moving alot more then usual today and his movements have been quite sore, about 4-5 times i have heard a click come from my stomach (not hips or anything) and im wondering what this is from? I just want to meet my little one and believe i am in preterm labour but dont want to get my hopes up about the fact that i have had more today then the other days. Sorry its long and thanks for the help :)
