I work as a tech at a vet clinic and we had somebody bring in a very sweet stray that they thought may be pregnant. Well she had been there about an hour and I went to get her from the little townhouse where we had her. She was laying in her litter box, just chilling. So I got her out and was turning around to walk to the treatment room with her and Doc starts screaming "It's alive!" I looked down and she has a kitten hanging out!!! We quickly got her and baby (still attached) to the back and helped clean the little one up (covered in litter!) She went on to have 2 more babies throughout the afternoon. Mom and babies are doing splendidly. There is an all white with a black spot on it's head, an orange and white marble tabby, and a little brown tabby. Adorable. Momma was so wonderfully tolerant of us! She just rubs and rubs on us and rolls over as if to say "Hey, look what I did! Aren't they cute?" I called the client that had brought her in and said "Well, she was pregnant!" She asked if we were sure and I just laughed. 
I think you're sure
