me n my gf were fooling around,we never did intercourse but i ejaculated over her vagina.Now after 10 days she had her period n in the next mnth also but on 3rd mnth she didnt had a period,which us to worry about what we did 3 mnths back.So is it possiable that she can b pregnant without having a intercourse n what cn b her period missing reason...she didnt had period frm last 11 days.
