Woman following a tuhr cycle every month
Q:
1. Do women have to follow their tuhr cycle every month? I do not have a fixed tuhr period. Some months it is 20 days, 21 days, then another month 16 days. I may get a same tuhr period for two months sometimes. But most of the time it is unfixed. For years I am counting my periods like this - if I get a bleeding after 15 days from the last period, I treat it as period. Can you please tell if this is the correct way of calculating periods or do I have to follow my previous month’s tuhr period?
2. Almost a year ago. it happened that I forgot my habit of period. I forgot how many days it was. After much contemplation, I felt that my habit was 8 days. Since then, I have been practicing upon it. Is that correct?
