It is difficult to say at this stage whether she had a miscarriage
except for some faint hints like the state of the cervix
and so on. Had it been at the time of the incident, blood tests for the serum beta-hCG
titres would have definitely revealed if she was pregnant. Even after a miscarriage the hormone levels do exist for some time before dropping down and thus give conclusive evidence on pregnancy
. Hope your query has been answered. Take care.
