Hello sir, me and my friend did masturbation (deep fingering) on 4th april, as far as we remember we didn't touched pre-come or sperms while fingering. Her periods were due on 27 of april but didn't come. After a week and 2 weeks delay of period we did home urine pregnancy test but all result were negative. The very next day 15 day after period delay she had bleeding like normal periods but bleeding lasted for 1 day only. Now we are very tensed is she pregnant? she is still having back pain like periods only. Please give guidance to us.
