How do I know if female stray I took in is pregnant by my dog?

Okay so I took a female stray dog off the streets to save her life. I could see her ribs and she had matted down fur. I have a male dog that has humped her like crazy. I have noticed that she has gained some weigbt, not too much but noticeable. Is it possible she pregnant?
Asked Apr 28, 2014
Yes she could possible be. Go tone vet and get a scan.
Answered Apr 28, 2014
I can't afford a scan right now.
If she is taken in though after life threatening condition it may be essential for her life and the potential pups to make sure everything is alright
Maybe you could feel yourself her belly and feel if any thing moves and give your a worming tablet she should have worms
