My Rabbits just Bred????

Ok i just now came in from what happened, i was outside and i have 3 rabbits. One male and two females. Rain, one of the females, and erscotch, the male had fallen in love the other day when i got the females. Chica, the other female, refuses to come out of the cage and play in the rabbit pen that i have set up. I let the male and the females play SEPERATLY on different occasions. (Male once, then put him back, and then let the females out.) Well just a second ago i let the Rain and Chica out and once again Chica stayed inside and Rain wondered around while i sat on the hay bale and watched her funny little kicks in the air. erscotch was watching from inside his cage and for some reason had this look in his eye. He bashed threw the cage door and ran towards Rain underneath the cage, where i couldnt reach him. Both unspaid and unneutered, he mounted her three times and she let him. His eyes rolled back into his head in enjoyment of i beleive. So, is she preganant???
