Running out of colostrum??

Hey lovelies! Was just wondering whether you can run out of colostrum prior to giving birth?? Not only do my nips leak a lot but I do a lot of nipple stimulation (trying to bring on labour to no avail) and I am producing a lot of colostrum, was just wondering whether it’s possible to run out prior to my babies birth?? (Any tips to bring on labour would be greatly appreciated) 👶🏼
