Dear user, welcome to healthcare magic.
I don't think you need to worry at all for the following reasons:
- she was not ovulating as you say.
- you did not penetrate nor ejaculate.
- she received emergency pills in the first 24 hours at which these pills are 95% effective.
So, the possibility of your girlfriend being pregnant is very remote.
is a disaster that should be prevented by any means you may apply an intrauterine device
Take care next time by using condoms or a local spermicidal.
