Wa alaikum salam wa rehmatAllah,

This is permissible.

Assalamualaykum wa rahmatullahi wa barakatuh Sheikh. Is it permissible for me to intend to fast any 3 consecutive days in a lunar month when I suspect I will likely be unable to observe the fast of the white days due to menstruation during those days? Jazakallahukhayran
