Thanks for follow up query.
Late period with red mucous discharge to heavy bleeding may be associated with early miscarriage
(mistaken as normal period).
In that case, bleeding will be there until process of miscarriage is completed. However, other uterine pathology like polyp or fibroid
imbalance, stress, pelvic infection
etc can cause this type of bleeding.
Therefore, I suggest to undergo above mentioned tests for confirmation. It will be more helpful to decide next level of management.
Hope, it helps for you. Kindly, close the discussion.
All the best and good luck.
