بسم الله الرحمن الرحيم
(Fatwa: 1350/L-459/TL=11/1434)
Istikharah should be done by the concerned person. If the heart does not tend in first time then it is better to do istikharah for seven days. If your heart does not tend after seven days then you may also do istikharah even some more days. Your heart shall however have a disposition after all, in-shaAllah.
Allah knows Best!
