As a physician patient ask me if non menstrual bleeding in the middle of the month is considered forbidden to have intercourse with the husband and have to wait 7 clean days.
How do you differentiate between kosher bleeding and bleeding that requires 7 days.
Any menstrual bleeding, even if in the middle of the month, renders a woman forbidden to her husband.
The only type of bleeding that does not render a prohibition is bleeding whose cause can be identified as stemming from a superficial wound (which is done by internal inspection). Beyond this, middle-of-the-month bleeding forbids a woman and the usual procedure of taharah must be employed.
