Will my mini rex bunny be pregnant?

This is my bunny, Priscillas 2nd litter. The first one died. I mated Priscilla with my male bunny, Elvis. I was going to sell Priscilla's litter at the grange fair (only in centre hall PA and I show rabbits at the fair.) but they died so I decided to breed them again. They where breeding for one hour and 7 minutes. Then I put Priscilla back in her hutch. Will she have babies? Is that long enough? If she will, how many babies will she have? Last time they mated for 30 minutes and she had 5 dead babies. Is she pregnant??????????
