This was happened on 10th February ,2018. I ejaculated on my gf leggings and she had also worn her panties at that time. After some time I fingered her . During fingering my nails hit her and she bled. she was all wet and I thought there may be any sperms on my finger. I didn't enter her and didn't contact her genitals with my penis. There were her leggings between us all the time. I did not do  any intercourse with her till date . I haven't had sex with her. This was all foreplay. She is 7 days  delay on her periods. Is there any chances of pregnancy. Her last period date is 20 January.
