sticky when doing push and pulls?

so i made a batch of dough today and it came out the blow cleanly with no sticking what so ever, but when i starter to do my push and pulls, my dough got sticky again. is my dough bad or is it supposed to get sticky? am i not using enough flour on the surface? started the process at 1040am waited an hour did 4 sets of stretch and folds every 30 minutes and after the last one (147pm) let it sit without being touch until i just shaped it 5 minutes ago. TIA
