HI, thanks for using healthcare magic
It is very understandable to be distressed about the idea of a miscarriage
Ovarian cysts can cause pain and irregular periods
. They are not normally associated with pv bleeding.
Unfortunately with a history of a positive pregnancy
test and subsequent abdominal pain
and vaginal bleeding, a miscarriage is most likely.
I appreciate that this may be difficult for you. You would need to follow up with your doctor as suggested by the ER staff.
I hope this helps and wish you the best
