Hi Doctor. I Met A Girl Recently And Had First

Hi Doctor. I met a girl recently and had first date. She lured me to make love. We did not have an intercourse but she did grind on my penis (with penis head open but ). Later I saw her panties were wet. She told me that it's my fluid. Later I came to know that she was on some continuous period issue. Can it be the case that her blood from pad came out and wet the panty. If my penis head with the foreskin drawn might have touched that fluid on panty during the grinding. Will that be a risk. Please help me
