My girlfriend's period is 8 days late.

What are the chances of my girlfriend being pregnant? We made out on December 31 2019. We used a condom & there was no penetration at all. She touched me while I was wearing the condom & then after some time touched herself. We checked the condom for damages and we did not find any. There was no penetration atall throughout the whole time. When I ejaculated at the end, I did not ejaculate on her and she was also wearing 2 layers of clothes when I ejaculated on my own stomach. Whenever we have been physically intimate, we have always made sure we have a at least 2 layers of clothing barrier every time. She was expecting her period on 4th of January 2020 but it has not yet come. She says she feels all the cramping and mood swings and also has a white discharge like she gets before every period. She says she can feel like her period is on its way but it's not coming. She has been regular with her periods for last 6 months. She is scared about having some hormonal imbalance.
