You really did not give enough information to help, but I will try anyway to lend soem guidance.
First, the bubbles being mounded really doesn't mean anything except the male has built a nest. Next, if the eggs were layed your female would likely be beaten senseless or dead. The key to look for is the males putting eggs back into the nest. He will go to the bottom and pick up one or more and redeposit them in the nest. If you don't see him tending the underside of the nest they are not done yet.
I've breed bettas so here is the scoop that I know. First, you never said if the female was conditioned? She should be swollen and have a white dot on her underside if she is ready to spwan. Next your tank set up, what is it? I would not have over 6" of water in it and would have places for the female to dodge the male. I use plastic sweater boxes and introduce the female from the safety of a mason jar. I release the female after allowing the male to display for two days and don't feed the male during the process. I never leave them together over 24 hours. Once you introduce the female put the mason jar back in with water in it and place it near a corner. The jar will allow the female to swim away from the male and he will be too worked up to figure out there is a jar in the way.
Once they have spawned remove the female and give it 3-4 days for the fry to hatch out and become free swimming. Remove the male and start the green water for food.
