Looks like the sac opened. I'd say you'll have some seeds. I'd immediately and carefully remove the sac. The damage is done, do you have a crop ready to start? If not, I'd wipe the area down if it's easy enough, grow it out for personal and friends, or a easy Xmas present. The resulting seeds in the batch will be likely ~85% female, but easily turn the herms if stressed (from my understanding). But free fem seeds are free fem seeds.
Just remember to check constantly for more sacs, at least every two days.. Preferably every day...
just one mans opinion,
