As-salamu alaykum dear sister,
Yes, this is a common problem, and as women, we often feel a loss. However, Allah SWT in His mercy lets us make up the days we missed. While that does not ease the loss we feel during the very blessed month, we are able to gain joy and satisfaction in doing works of charity, helping others, giving, preparing meals and feeding others , and being of service to the needy. Insha’Allah sister, try to focus on your service to Allah and those around you during your menses. Your acts of loving charity will carry great weight insha’Allah. I hope this helps sister, Ramadan Mubarak!
