Get physical without penetration. Case?

Dear sir/mam, i got engaged in a physical relationship with my girlfriend on her fertile period. We do makeout without penetration. And also i did not ejaculate near her vagina and we both wash hands after my ejaculation. But our genitals are rubbed with each other multiple times during making out. Now her period date is one day late. She is feeling stomach cramps and a white cervical mucus as she always feels 2-3 days before her menstrual cycle starts. But her periods are not came yet they were expected yesterday but they haven't came yet. Please tell me what to do. We can't afford child now as we are unmarried and that's why i am very stressed. Please tell me what to do. Is there any chances of getting pregnant in my case?
