Hi, I Hope Someone Can Help Me With This So

Hi, i hope someone can help me with this so i can have a peace of mind.

My girlfriend started her lmp sept 11 and we ha unprotected sex sept 22 at 11:40 pm. I ejaculated outside of her and wiped the sperm off of my penis with a hanky and after 15-25 secs i immediately inserted it back in. I still didnt ejaculate inside her on the 2nd time. My girlfriend had spots on the next day and had abdominal cramps, i thought it was because it was our first time. And i realized that she might have started ovulating. On sept 25, i got worried and tried to do a research and found out that even if you wiped semen off of your penis, there are still some of it left. So i tried to search for ECPs available in the Phils and found out about Nordette. At 7:40pm, my girlfriend took her 1st dosage and the 2nd 12 hrs after. Is there a chance that the Nordette prevented pregnancy even if the sperm might have started to fertilize the egg? Please answer, i barely have enough sleep worrying. Thanks
