Help Yellowish red unrine after takin postinor

Patient: Hi, Im twenty this year. I took postinor two for the ist time, eighteen hrs after my bf pre-cum near my vagina. The next morning, I found that I have dark yellowish red urine. Im a virgin but my bf had fingered me, and had precum near my vagina, there were no ejaculation inside my vagina that’s why I took postinor two. Is the urine colour due to the fingering or postinor two? And is it normal? Is it okay to take postinor two in this situation? Thank you.
