Answer
Yes, I would say she probably is pregnant.  You need to learn some responsibility.  Why arent your dogs neutered? Learn to spell. You let your dog escape?? What is wrong with you? Do the dogs a favour,  and rehome them to someone who has a clue about dogs. Your dog shouldn't be throwing up, take her to the vet NOW.
