Can fingering delay my gf's period?

So me and my girlfriend were playing around on April 20 (the day that her period was suppose to come). I fingered her but she didn't even come on top of me or anything and even like that I had a condom on. But she didnt have her period yet and I am a little worried about it. Could fingering my girlfriend delay her period? If so, for how long? She told me today she is having some cramps so I think her period will come. I just told her to relax and try to concentrate on other things, would that be effective for her period to come?

Please I need to know about it ASAP.

Thank you.

P.S.: we did dry-hump like 2 weeks before we did this but i had a condom on and i came in it but i didnt even touch her with it. I changed my condom and I made sure I didn't touch any parts that had sperm on the other condom and I washed my hands before I fingered her 2 weeks before April 20.
