After few mintus he took his organ out side and he started masturbating himself and he released his sperm on my body ( stomach ) and after 10hr i look i pill to be in safer side,  after 5 days i started bleeding heavy it continued  for 7 days,  then later bleeding  itself stopped, Now question is there any chance geting pregnancy? While wash ing sperm with water does sperm transfer through water and then it might gone inside vigina?  Is there any chance of getting pregnancy...?? It already one month now but missed my date....what should i do now? Please tell me, With Respect, **************
