My question is I recently started a pill to delay my periods, however they did not work and my periods came 9 days late. I usually have a fixed duration (6 days), although not always the same date. However, I am currently on my 10th day of bleeding. I have two questions,

1) When do I start the count of istihada from?
2) When am I able to have intercourse with my husband, when the bleeding stops or during istihada?

1- If the bleeding passed the 10th day, then all the days above the 6 days are Istehadha.
2- You can have the intercourse during Istehdha.
