my period duration is more than 10 days? which days should I not count,(for ibadat) , either starting days, ending days or both in which there is no flow just indication and little bit spoting…
I offer adaa and qaza both nmaz for these extra days due to doubts….

Minimum of 3 days and maximum of 10 days will be considered haydh

Anything after that you will consider it to be istihadha and follow the rules of istihadha for them
