Irregular discharge

Q: I had a problem of irregular discharge. I used to experience yellow discharge almost every day. Depending on my previous habit, I used to count my tuhr days as 23 and my period days as 8. Last month, after my period ended on 29 January. I experienced discolored discharge on 30 and 31st January. Then I was totally clean for 15 days. After that I started bleeding on 15 February. I counted it as my period. And it ended on the 10th day on 25th February.

1. Was it correct for me to count my period from 15 February?

2. What will be my new tuhr habit and period habit?

Irregular brown discharge after taking birth control pills

Q: I am usually regular with my menstruations, with active bleeding occuring around the 20th of each month, once a month only. However I have recently started taking birth control pills, and I am experiencing a very mild brown discharge, since the 7th November (out of my regular menstrual bleeding time). Medically this is referred to as breakthrough bleeding, caused by the pill. Would it be counted as menstrual bleeding Islamically, once 15 days of being paak have passed? Even though this bleeding does not exactly resemble the actual menstrual flow? What about if this brown discharge starts before the full 15 days of being paak,i.e. the discharge occurs randomly throughout the month. Although, during the first 2 days of my actual menstrual period, the flow is a similar mild brown, after which it progresses to red bleeding.
